Subject: [PATCH] Remove configure check prohibiting threaded libpython on
 OpenBSD.

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.
