Update: cherry-picking commit 96673a4bb36 on top of perl's v5.42.0 tag
fixes the problem. I can confirm that perl's "make test" passes. People
in #perl on libera.chat seem to think this is a reasonable approach.

I have not tried applying the fix in pkgsrc, but hopefully it should be
as simple as adding a patch from commit 96673a4bb36.
