acinclude.m4 (LIBGFOR_CHECK_FOR_BROKEN_ISFINITE, [...]): Remove.
* acinclude.m4 (LIBGFOR_CHECK_FOR_BROKEN_ISFINITE,
LIBGFOR_CHECK_FOR_BROKEN_ISNAN,
LIBGFOR_CHECK_FOR_BROKEN_FPCLASSIFY): Remove.
* configure.ac: Remove above checks.

signbit in terms of the respective built-ins.
* io/write_float.def (WRITE_FLOAT): Use signbit() instead of
__builtin_signbit().
* intrinsics/c99_functions.c (tgamma): Use isnan() instead of
__builtin_isnan().
