Using newer versions of binutils to compile GRUB results in the
stage2 image being corrupt. This results in the message
"Error 6: Mismatched or corrupt version of stage1/stage2"
when installing grub. For example, this could occur if using a
crosstool-ng glibc toolchain targetting Linux i686.

The problem is mentioned on the Buildroot bug tracker [1] and
on the OpenWRT bug tracker [2].
