I don't know if there's an easy way to test if regexec() on your
system supports locale (at least for is_IS). I can reproduce the same
by using compat regex. So it's not a good news because compat regex is
used in a few platforms, so this test will fail on those.

I don't see any way around it, except dropping all the tests. I don't
think there is a way for us to test regex locale support at runtime.
