this will serve for now with less churn.

math.h: Define FP_FAST_FMA, FP_FAST_FMAF, FP_FAST_FMAL.

These are not strictly necessary to define, really, so we haven't
exactly been nonconformant. But they tell programs when they can
enable fast paths by using the fma(3) family of functions.

It seems that we need prototypes for long double math functions, even
when !__HAVE_LONG_DOUBLE -- they still exist, but just aren't...

This might unbreak several more builds.

This set of changes seem to be sufficient to make at least the
amd64 port build again after the long double math function infusion
from yesterday.

This set of changes seem to be sufficient to make at least the
amd64 port build again after the long double math function infusion
from yesterday.

Feel free (without consulting me, I'm just hacking about) to revert
any of this and do it a better way.

Note: this is not intended to be complete, in particular, in <math.h>
I added prototypes only for the functions that are needed for a
successful build, not all of the new ones...
