Since the GRUB2 tools built using a Linux GCC compiler will suffice at

will be needed to accomplish this goal.

Would be alright if we could enable execute permission only on the specific

Hello,
There is another issue with GRUB2 on OS X which I am not sure has
been brought up yet.
Right now, AFAIK (but I haven't tested it), GRUB2 (the part that runs
from OpenFrimware) can be built
with a bootstrap powerpc-elf-targetted GCC hosted on OS X. However,
