We probably need to generate a config define to indicate that we've found this case - because we will also need some specs magic to ensure that "-Q" is _only_ forced for -gstabs* otherwise folks will lose the ability to assemble AVX, which I suspect is far more interesting to most people than support for debugging on darwin8 ;-)
