If it is then even without this change you wouldn't have have got the 
EFI loader or boot1, just an unused libefi.

This change ensures that builds with in-tree Clang and GCC build on all 
platforms, even if GCC doesn't build the EFI components.

If someone that uses none in-tree GCC has some time to dedicate to make 
this work that would be great :)
