alpha: Fix redefinition of __isnanl macro warning

In bdd7898a58bd76ac3b411a4931ff3f9e77eabe6a we added self-definitions
of __isnan and friends in order to indicate specialized architecture
support, and avoid redefinitions within various generic math_private.h.

There is no generic math_private.h that concerns ldbl-128, and while
we provide __isnanl in the alpha math_private.h there's no need to
protect the function against redefinition.
