float128: Add _Float128 make bits to libm.
This adds the appropriate common bits for a platform to enable float128 and expose ABI. * math/Makefile: (type-float128-suffix): New variable (type-float128-routines): Likewise (type-float128-yes): Likewise (types): Append float128 if supported (types-basic): New variable to control the use of templates for float, double, and long double, but not for float128 or newer types. (type-basic-foreach): Likewise. * sysdeps/ieee754/float128/Makeconfig: New file. * sysdeps/ieee754/float128/Versions: New file.
