strip the kernel version suffix from target directories, except for brcm-2.4 (the -2.4 will be included in the board name here). CONFIG_LINUX_<ver>_<board> becomes CONFIG_TARGET_<board>, same for profiles.

++	bool "Use GPIO for i2c instead of built-in TWI module"
++	help
++	  The driver for the built-in TWI module has been plagued by

++	  trusty old i2c-algo-bit bitbanging engine, making it work
++	  on pretty much any setup.
