math: support platforms with limited FP rounding or exception support
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.
