Yes, it does. I did try back when I first added the cross compiler
support, but for some reason did not manage to make use of the built-in
cross compilers. Maybe the versions in that Ubuntu version were just too
old? I really don't remember.

I'll be more than happy to see you make them work though :).

They seem to work surprisingly well for grub, given that we're even
doing execution tests against a few of the resulting binaries ;).
