Subject: [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)
