I need to find time to argue for USE flags sometime.  In short 'tho, you
only end up with 2 grub packages that differ if, well, you want them to.
Distros (Angstrom) that let people install stuff on the system from
feeds should do something like:
### DO NOT CHANGE ANY OF THE FOLLOWING IF YOU INTEND TO PUBLISH YOUR
### PACKAGES.  DOING SO WILL BREAK PEOPLE.
USE_FLAG_1 := ...
USE_FLAG_2 := ...

And distros that really want to USE (or not USE) something can set them
differently, and we don't end up with N permutations of recipes that
people have to mind when fixing things nor forking for their own use the
recipes and stripping things out.  It's really two sides of the same
coin.

Unrelated, this should be ${GNU_MIRROR}/grub/grub-${PV}.tar.gz
