		help
		  If your target CPU does not have a Floating Point Unit (FPU) or a
		  kernel FPU emulator, but you still wish to support floating point
		  functions, then everything will need to be compiled with soft floating
		  point support (-msoft-float).

		  Most people will answer N.

		depends on HAS_MIPS16
		default y
		help
		  If your target CPU does support the MIPS16 instruction set
		  and you want to use it for packages, enable this option.
		  MIPS16 produces smaller binaries thus reducing pressure on
		  caches and TLB.

		  Most people will answer N.

		  If you're specifying an addition target architecture,
		  you'll probably need to also provide options to make
		  the compiler use this alternate arch.

		  For example, if you're building a compiler that can build
		  both powerpc and powerpc64 binaries, you'll need to
		  specify -m64 here.
