According to recent tests, this case now works fine, so there's no reason to reject it anymore. (Even if there are still some OpenBSD platforms in the wild where it doesn't work, removing the check won't break any case that worked before.) We can actually remove the entire test that discovers whether libpython is threaded, since without the OpenBSD case there's no need to know that at all. Per report from Davin Potts. Back-patch to all active branches.
