You are trying to enable IMAGE_COMBOOT, which is conceptually impossible 
on EFI since it's intrinsically a BIOS-only format.

No.  If you check out a clean copy of the iPXE code, then a sensible set 
of default targets (including bin-x86_64-efi/ipxe.efi) will build correctly.

As a general rule for everyone (on pretty much any codebase): if you get 
a build failure then the first thing you should try is removing any 
build customisations you have made.
