So I tried to make a small reproducer, and failed.  Then I ran the
buildfarm script (with abidiff enabled) against c6881f79228,
right before the last .abi-compliance-history update, and it passed.
IOW, the version of abidiff I have here does not seem to have this
bug.  It's 2.8.0 from last July or so.

Now I'm wondering exactly what libabigail releases crake and baza
are using.
