Patches for compiling glibc-2.6.1 with an up to date toolchain.

README

Patches to compile (crossdev) glibc-2.6.1 with an otherwise up to date (~arch) toolchain (binutils 2.23.1, gcc 4.7.2)

Tested with armv6j-hardfloat-linux-gnueabi and x86_64-bindist-linux-gnu targets.

cross-i686-bindist-linux-gnu/glibc failed with gcc 4.6 and 4.7, but worked with gcc 4.5
