Yeah, there's a bug report for this here,
https://bugzilla.kernel.org/show_bug.cgi?id=43309
I suspect that older firmware doesn't handle a zero .reloc section
properly. So, unfortunately we will have to leave the .reloc section
with a dummy reloc, rather than having one with no entries.
I'll put a patch together.
