Move this test to a more sensible place.  Originally it was intended
to check that the threading library hadn't messed up errno.  Now that
doesn't make much sense any more.  Anyway, now it annoyingly fails due
to memcheck reporting bugs in libpthread et al.  Move it to corecheck
so at least it can continue to run and hopefully not continually fail.
