Hmm. I checked not too long ago, and these are the buildfarm
animals that would be broken:

prairiedog | 2022-03-23 05:04:02 | configure: using perl 5.8.3
anole | 2022-03-24 10:40:08 | configure: using perl 5.8.8
gharial | 2022-03-24 18:32:22 | configure: using perl 5.8.8
locust | 2022-03-19 22:17:53 | configure: using perl 5.8.8
gaur | 2022-03-19 15:00:54 | configure: using perl 5.8.9

I could update prairiedog and gaur (... probably), but hard to say
about the others.

It seems kind of sad for a backwards-compatibility patch to force a
major move of our minimum Perl version. OTOH, if there's no other
good way to do it, maybe we gotta.

Another possibility is that maybe parent.pm could be successfully
installed into a 5.8.x installation. I can't speak for those
other animals, but mine at least are already frankencritters.
