grub autoconf log file

When buildroot is configured for x86_64 as the target architecture, grub configuration fails with the following error message:

checking for x86_64-linux-gcc... (cached) /home/user/Downloads/buildroot-2012.02/output/host/usr/bin/x86_64-unknown-linux-uclibc-gcc
checking for C compiler default output file name... configure: error: C compiler cannot create executables
See `config.log' for more details.
make: *** [/home/user/Downloads/buildroot-2012.02/output/build/grub-0.97/.stamp_configured] Error 77

The problem seems to be that the 32-bit libraries are not available (or used) in the 64-bit cross-compiler toolchain.

I've posted a series of patches at http://lists.busybox.net/pipermail/buildroot/2013-November/082351.html that fix this problem.

The patch series has been committed now.
