I would have thought that package developers would usually want to make
two separate packages for the i386 and x86_64 headers/libraries. Either
way, that's a distro-specific choice. For the record, most people will
want to be building for x86-64 anyway because there are so few i686 EFI
firmware implementations in the wild.

You can already build just x86_64 with 'make efi64'. For more info see
doc/building.txt in the 6.xx source.
