Reading this, it occurred to me that it'd be interesting to scrape
all of the latest configure results from the buildfarm, and see which
tests actually produce more than one answer among the set of tested
platforms. Those that don't could be targets for further simplification,
or else an indicator that we'd better go find some more animals.
Before I go off and do that, though, I wonder if you already did.
