Grub 2 has support for EFI, yet the ebuild doesn't support it and just builds the BIOS variant. I'd really like to have a proper EFI installation in portage, preferably enabled by USE=efi.
This is already implemented in Bug #291851.
Steps to Reproduce:
1. emerge >grub-1
Builds the BIOS version on x86.
Build the EFI version.
