[Ada] Ada.Numerics.Aux.*: Mention more Intrinsic and less C Math Library
Since we import the elemental math functions as intrinsics, it's not
accurate to state we're drawing them in from the C math library.
gcc/ada/
* libgnat/a-nagefl.ads: Replace mentions of C/unix math library
with intrinsics.
* libgnat/a-nallfl.ads: Likewise. State compatibility
requirements.
* libgnat/a-nalofl.ads: Likewise.
* libgnat/a-nuaufl.ads: Likewise.
