-	default y
-	help
-	  This option group includes functions for producing a list of
-	  the function calls that are currently active in a thread, from
-	  within the thread itself.  These functions are often used
-	  within signal handlers, to produce diagnostic output.
-
-	  This option group includes the following functions:
-
-		backtrace
-		backtrace_symbols
-		backtrace_symbols_fd
-
-
-config EGLIBC_OPTION_EGLIBC_BIG_MACROS
-	bool "Use extensive inline code"
-	default y
-	help
-	  This option group specifies whether certain pieces of code
-	  should be inlined to achieve maximum speed.  If this option
-	  group is not selected, function calls will be used instead,
-	  hence reducing the library footprint.
-
-
-config EGLIBC_OPTION_EGLIBC_BSD

-	bool "Tests that link against the standard C++ library."
-	default y
-	select EGLIBC_OPTION_POSIX_WIDE_CHAR_DEVICE_IO
-	select EGLIBC_OPTION_EGLIBC_LIBM
-	help
-	  This option group does not include any C library functions;
-	  instead, it controls which EGLIBC tests an ordinary 'make
-	  tests' runs.  With this group disabled, tests that would
-	  normally link against the standard C++ library are not
-	  run.
-
-	  The standard C++ library depends on the math library 'libm' and
-	  the wide character I/O functions included in EGLIBC.  If those

-
-	  This option group includes support for character sets other
-	  than ASCII (ANSI_X3.4-1968) and Unicode and ISO-10646 in their
-	  various encodings.  This affects both the character sets
-	  supported by the wide and multibyte character functions, and
-	  those supported by the 'iconv' functions.
-

-	help
-	  This option group provides ultra fast DES-based implementation of
-	  the `crypt' function.  When this option group is disabled,
-	  (a) the library will not provide the setkey[_r] and encrypt[_r]
-	  functions and (b) the crypt[_r] function will return NULL and set the
-	  errno to ENOSYS if /salt/ passed does not correspond to either MD5,
-	  SHA-256 or SHA-512 algorithm.

-	  following functions:
-
-		endaliasent
-		getaliasbyname
-		getaliasbyname_r
-		getaliasent
-		getaliasent_r
-		setaliasent
-
-	  When this option group is disabled, the NSS service libraries
-	  also lack support for querying their mail alias tables.
-
-
-config EGLIBC_OPTION_EGLIBC_ENVZ
-	bool "Functions for handling envz-style environment vectors."
-	default y
-	help
-	  This option group contains functions for creating and operating
-	  on envz vectors.  An "envz vector" is a vector of strings in a
-	  contiguous block of memory, where each element is a name-value
-	  pair, and elements are separated from their neighbors by null
-	  characters.
-
-	  This option group includes the following functions:
-

-
-config EGLIBC_OPTION_EGLIBC_FSTAB
-	bool "Access functions for 'fstab'"
-	default y
-	help
-	  This option group includes functions for reading the mount
-	  point specification table, '/etc/fstab'.  These functions are
-	  not included in the POSIX standard, which provides the
-	  'getmntent' family of functions instead.
-
-	  This option group includes the following functions:
-
-		endfsent       getfsspec
-		getfsent       setfsent
-		getfsfile
-
-
-config EGLIBC_OPTION_EGLIBC_FTRAVERSE
-	bool "Functions for traversing file hierarchies"
-	default y
-	help

-	help
-	  This function group includes the 'getlogin' and 'getlogin_r'
-	  functions, which return the user name associated by the login
-	  activity with the current process's controlling terminal.
-
-	  With this option group disabled, the 'glob' function will not
-	  fall back on 'getlogin' to find the user's login name for tilde
-	  expansion when the 'HOME' environment variable is not set.
-
-
-config EGLIBC_OPTION_EGLIBC_IDN
-	bool "International domain names support"
-	default y
-	help
-	  This option group includes the `libcidn' library which
-	  provides support for international domain names.
-
-
-config EGLIBC_OPTION_EGLIBC_INET
-	bool "Networking support"
-	default y
-	help
-	  This option group includes networking-specific functions and
-	  data.  With EGLIBC_OPTION_EGLIBC_INET disabled, the EGLIBC
-	  installation and API changes as follows:

-config EGLIBC_OPTION_EGLIBC_LIBM
-	bool "libm (math library)"
-	default y
-	help
-	  This option group includes the 'libm' library, containing
-	  mathematical functions.  If this option group is omitted, then
-	  an EGLIBC installation does not include shared or unshared versions
-	  of the math library.
-
-	  Note that this does not remove all floating-point related
-	  functionality from EGLIBC; for example, 'printf' and 'scanf'
-	  can still print and read floating-point values with this option
-	  group disabled.
-
-	  Note that the ISO Standard C++ library 'libstdc++' depends on
-	  EGLIBC's math library 'libm'.  If you disable this option

-config EGLIBC_OPTION_EGLIBC_LIBM_BIG
-	bool "Math library size"
-	default y
-	help
-	  This option group enables default configuration of the math library.
-	  Not selecting this option group removes most of the extended and
-	  double precision math functions and replaces them with wrappers
-	  to the single precision couterparts.
-	  Doing so greatly degrades quality of calculations carried
-	  out by the functions of the math library, but also significantly
-	  reduces the size of the libm.
-	  This option group is useful for systems that do not rely on precise
-	  floating point math.

-	  EGLIBC supports only the 'C' locale (also known as 'POSIX'),
-	  and ignores the settings of the 'LANG' and 'LC_*' environment
-	  variables.
-
-	  With EGLIBC_OPTION_EGLIBC_LOCALE_CODE disabled, the following
-	  functions are omitted from libc:
-
-		duplocale   localeconv  nl_langinfo    rpmatch  strfmon_l
-		freelocale  newlocale   nl_langinfo_l  strfmon  uselocale
-
-	  Furthermore, only the LC_CTYPE and LC_TIME categories of the
-	  standard "C" locale are available.
-
-	  The EGLIBC_OPTION_EGLIBC_CATGETS option group depends on this option

-
-	  EGLIBC_OPTION_EGLIBC_MEMUSAGE_DEFAULT_BUFFER_SIZE
-
-	  Libmemusage library buffers the profiling data in memory
-	  before writing it out to disk.  By default, the library
-	  allocates 1.5M buffer, which can be substantial for some
-	  systems.  EGLIBC_OPTION_EGLIBC_MEMUSAGE_DEFAULT_BUFFER_SIZE option
-	  allows to change the default buffer size.  It specifies
-	  the number of entries the buffer should have.
-	  On most architectures one buffer entry amounts to 48 bytes,
-	  so setting this option to the value of 512 will reduce the size of
-	  the memory buffer to 24K.

-config EGLIBC_OPTION_EGLIBC_NSSWITCH
-	bool "Name service switch (nsswitch) support"
-	default y
-	select EGLIBC_OPTION_EGLIBC_INET
-	help
-
-	  This option group includes support for the 'nsswitch' facility.
-	  With this option group enabled, all EGLIBC functions for
-	  accessing various system databases (passwords and groups;
-	  networking; aliases; public keys; and so on) consult the
-	  '/etc/nsswitch.conf' configuration file to decide how to handle
-	  queries.
-
-	  With this option group disabled, EGLIBC uses a fixed list of
-	  services to satisfy queries on each database, as requested by
-	  configuration files specified when EGLIBC is built.  Your
-	  'option-groups.config' file must set the following two
-	  variables:
-
-	  EGLIBC_OPTION_EGLIBC_NSSWITCH_FIXED_CONFIG
-
-		Set this to the name of a file whose contents observe the
-		same syntax as an ordinary '/etc/nsswitch.conf' file.  The
-		EGLIBC build process parses this file just as EGLIBC would
-		at run time if EGLIBC_NSSWITCH were enabled, and
-		produces a C library that uses the nsswitch service
-		libraries to search for database entries as this file
-		specifies, instead of consulting '/etc/nsswitch.conf' at run
-		time.
-
-		This should be an absolute filename.  The EGLIBC build
-		process may use it from several different working
-		directories.  It may include references to Makefile
-		variables like 'common-objpfx' (the top of the build tree,
-		with a trailing slash), or '..' (the top of the source tree,
-		with a trailing slash).
-
-		The EGLIBC source tree includes a sample configuration file
-		named 'nss/fixed-nsswitch.conf'; for simple configurations,
-		you will probably want to delete references to databases not
-		needed on your system.
-
-	  EGLIBC_OPTION_EGLIBC_NSSWITCH_FIXED_FUNCTIONS
-
-		The EGLIBC build process uses this file to decide which
-		functions to make available from which service libraries.
-		The file 'nss/fixed-nsswitch.functions' serves as a sample
-		configuration file for this setting, and explains its syntax
-		and meaning in more detail.
-
-		This should be an absolute file name.  The EGLIBC build
-		process may use it from several different working
-		directories.  It may include references to Makefile
-		variables like 'common-objpfx' (the top of the build tree,
-		with a trailing slash), or '..' (the top of the source tree,
-		with a trailing slash).
-
-		Be sure to mention each function in each service you wish to
-		use.  If you do not mention a service's function here, the
-		EGLIBC database access functions will not find it, even if
-		it is listed in the EGLIBC_OPTION_EGLIBC_NSSWITCH_FIXED_CONFIG
-		file.
-
-	  In this arrangement, EGLIBC will not use the 'dlopen' and
-	  'dlsym' functions to find database access functions.  Instead,
-	  libc hard-codes references to the service libraries' database
-	  access functions.  You must explicitly link your program
-	  against the name service libraries (those whose names start
-	  with 'libnss_', in the sysroot's '/lib' directory) whose
-	  functions you intend to use.  This arrangement helps
-	  system-wide static analysis tools decide which functions a
-	  system actually uses.
-
-	  Note that some nsswitch service libraries require other option
-	  groups to be enabled; for example, the EGLIBC_OPTION_EGLIBC_INET
-	  option group must be enabled to use the 'libnss_dns.so.2'
-	  service library, which uses the Domain Name System network
-	  protocol to answer queries.

-	help
-	  This option group enables debug output of the runtime linker
-	  which is activated via LD_DEBUG and LD_TRACE_PRELINKING
-	  environment variables.  Disabling this option group yields
-	  a smaller runtime linker binary.
-	  BEWARE: Disabling this option group is likely to break
-	  the `ldd' utility which may also be used by the prelinker.
-	  In particular, the `--unused' ldd option will not work correctly.

-config EGLIBC_OPTION_EGLIBC_SPAWN
