Support defining strfromf64, strfromf32x aliases.
This patch adds support for defining strfromf64 and strfromf32x aliases of strfromd when the corresponding types are enabled. Tested for x86_64; also tested with build-many-glibcs.py in conjunction with other _Float64 / _Float32x changes. * stdlib/strfromd.c: Include <bits/floatn.h>. [__HAVE_FLOAT64 && !__HAVE_DISTINCT_FLOAT64] (strfromf64): Define and later undefine as macro and define as weak alias. [__HAVE_FLOAT32X && !__HAVE_DISTINCT_FLOAT32X] (strfromf32x): Likewise.
