float128: Include math-finite.h for _Float128
All the declarations in math-finite.h are macroized by floating-point type. This patch includes it for float128 and protects the declarations of functions that need not be declared for float128. * math/math.h: Include bits/math-finite.h for float128. (__MATH_DECLARING_FLOATN): Define to control declaration of float128 functions. * math/bits/math-finite.h (pow10): Do not declare for float128. (gamma): Likewise. (scalb): Likewise.
