IRIX long double: use the C99/C11-style generic math macros.
Without this the IRIX libmath _isinfl/_isnanl APIs are not used,
and the explicit comparison against NV_MAX/-NV_MAX is used instead,
which seems to work, but is definitely ickier and probably slower.
In the ideal world we could have a Configure test for these math macros.
