It's these dependencies on a symlink:
sys/boot/efi/boot1/Makefile:beforedepend ${OBJS}: x86
sys/boot/efi/loader/Makefile:beforedepend ${OBJS}: x86
A similar symlink is done for kernel modules but it avoids the problem
you're hitting through various fixes such as in r72935 and r315459.
I'll work on a fix. (It's unrelated to my recent changes)
