EFI PXE bootstrap and NBI image support

[anary]

It appears the build for EFI PXE Bootstrap (32 or 64-but) with IMAGE_NBI enabled is broken. I cannot build it locally, or with Rom-o-Matic.

Is there some inherent incompatibility with these options?

I need NBI image support because Clonezilla and DRBL still appear to use NBI images.

Here is the log from a Rom-O-Matic build which failed:

Code:
