x86_64 EFI support for grub2 ?

[Bean]

Hi,

I just wonder if anybody is working on x86_64 EFI support ? If none,
I'd like to add it soon, as it's essential for grub2 to work with
Apple's 64-bit Intel Mac.

BTW, I notice that grub-mkimage for efi convert elf to efi internally,
how about use the gnu-efi tool chain, this could make it more portable
between ia32 and x86_64.
