I reverted this change due to some problems with it.

Anyway, at the moment, this code cannot be shared because GRUB does
not support ELF64 binaries.  GRUB 2 will certainly support those, as
well as the new Multiboot format (still in development).  We'll be
able to make the code common to both platforms when this is usable.
