Use __builtin_signbit* with clang. * lib/math.in.h (signbit): Use __builtin_signbit{,f,l} also on clang. * m4/signbit.m4 (gl_SIGNBIT): Use __builtin_signbit{,f,l} also on clang. Set REPLACE_SIGNBIT_USING_BUILTINS, not REPLACE_SIGNBIT_USING_GCC. * m4/math_h.m4 (gl_MATH_H_DEFAULTS): Initialize REPLACE_SIGNBIT_USING_BUILTINS, not REPLACE_SIGNBIT_USING_GCC. * modules/math (Makefile.am): Substitute REPLACE_SIGNBIT_USING_BUILTINS, not REPLACE_SIGNBIT_USING_GCC.
