[massive] add support for alternative C libraries (currently only glibc/eglibc)
other (related) changes:
- kernel headers are now installed using "make headers_install" on 2.6
- target names now contain an openwrt "vendor" tag (e.g. mips-openwrt-linux-gnu)
- build directory names now contain gcc/libc name/version
- default cpu for x86 is now i486 (required to build glibc/eglibc)
