[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) git-svn-id: svn://svn.openwrt.org/openwrt/trunk@13931 3c298f89-4303-0410-b956-a3cf2f4a3e73
