Seeing as this continues the sentence from the subject, it should start
without a capital. Otherwise the result is werd to read.

Really? How can this be a legitimate transformation for the linker to make?

The content of .relocs is transformed via mkreloc to become
__base_relocs_{start,end} and shouldn't exist into the final linked
image AFAICT.
Since the MB1/MB2 builds aren't relocatable, I think we might be able to
get away with simply excluding them in the non-EFI build.
