This is known issue. xen.efi contains MB1 and MB2 headers because it is
build from almost the same source/object files. I tried to fix this once
but this is not easy. I am going to do that when current patch series is
applied. After that xen.efi will be loadable by three boot protocols.
Additionally, there is a chance that this way we will drop dependency
on specific binutils version.
