Patch I used to test with binutils-2.20.1
I ran into problems using buildroot to cross-compile mpc (and gcc-4.5.x for
which mpc is a dependency). The build would fail and the cross-compile-ld
would complain that it couldn't find /lib//libc.so.0
It turns out this is a bug in ld from binutils that was fixed in binutils 2.21:
https://bugs.launchpad.net/binutils/+bug/625320
Basically ld ignores the sysroot path when absolute library paths are given,
which causes errors when cross-compiling.
This issue affects any package that uses absolute library paths, such as mpc
and others.
The fix (which is basically this
http://bugs.gentoo.org/attachment.cgi?id=195936) ought to be added to the
buildroot patches for binutils versions prior to 2.21.
