As developers, we can blame the poor results on the platform's libm, but that doesn't help the user.

I would want the tests to fail, especially if it can occur on Linux (though I
still suspect an i686 router in the reported case).

Perhaps hide them behind -uall, so that *we* see the result but just
executing ./python -m test passes.
