This error message comes from recordmcount. It probably can't handle the missing STT_SECTION symbols which are getting stripped by the new binutils. (Objtool also had trouble with that.)
No idea why you only see this on 4.4 though.
Just taking a quick look, but would something like this work?
I created this against v4.4.257.

Thanks for the patch, but no, still fails with:
