2012-05-17math: support platforms with limited FP rounding or exception supportChris Metcalf
For some tests, just claim that fetestexcept() always returns true, so the rest of the test can be compiled. For libm-test, provide known bogus values for unsupported rounding modes, so fesetround() will return failure. Elsewhere, just add some #ifdefs to avoid code that uses particular FP exceptions if the exceptions aren't supported.
