Other questions:

 * What about using the host compiler to build Grub? I know it sounds a
   bit funky, but in practice, most Buildroot users will work on
   x86/x86_64 machines. If they are on x86, then it just works, if they
   work on x86_64, then most likely they have a multilib 32/64
   toolchain installed on their host. This would at least enable, for
   most users, the possibility of building Grub as part of a x86_64
   target system configuration.

 * What does Grub really require from gcc_s? Is it impossible to rework
   Grub to make independent from the compiler companion libraries?

Thomas
