I do not have either an efi machine or a gpt disk to know for sure, but
perhaps the following two applications may be of help in creating a EFI
binary:
* sys-boot/mbr-gpt
Available versions:
~ 0.0.1 "~x86 ~amd64"

Description: An MBR that can handle BIOS-based boot on GPT.
* sys-boot/gnu-efi
Available versions:
* 3.0a-r1 "ia64 x86"
~ 3.0e "~ia64 ~x86 ~amd64"
