Gross. I would not be opposed to a Makefile rule that outputs the
correct set of OBJECTS so this (or other) scripts could build on it.

IIRC, BSD make has an option to do this "make -V OBJECTS" or something,
but I don't thnk there's an easy way to do so.

Or, since it seems to find useful results quite frequently, maybe it
would be worth including the script inside git (and triggering it with
an optional Makefile rule). It sounds like we'd need a way to annotate
known false positives, but if it were in common use, it would be easier
to get people to keep that list up to date.
