  Ok; it's still not actually *contingent* on "do not have cxa_atexit".

  If problems with static ?tor ordering exists on more than one platform, I
see why it makes sense to consider it as a category.  But it really ought to
be true by default, other targets that aren't affected by this bug shouldn't
be excluded from the test on the basis of an overly-broad filter.
