Yes, or at least what's testing errno in it (which looks like pretty much the whole test). Or, better, add an effective-target keyword for math-errno support and restrict the test based on that (and convert any present skips of math-errno tests for Darwin to use the new effective-target keyword) - it's not the only system without math-errno support in its libm.
