Remove __signbit inlines from mathinline.h. Math.h already uses the builtin when supported, so additional inlines are only used on pre 4.0 GCCs. Similarly remove ancient copysign and fabs inlines. * sysdeps/alpha/fpu/bits/mathinline.h: Delete file. * sysdeps/ia64/fpu/bits/mathinline.h: Delete file. * sysdeps/m68k/coldfire/fpu/bits/mathinline.h: Delete file. * sysdeps/m68k/m680x0/fpu/bits/mathinline.h: (__signbitf): Remove. (__signbit): Remove. (__signbitl): Remove. * sysdeps/powerpc/bits/mathinline.h (__signbitf): Remove. (__signbit): Remove. (__signbitl): Remove. * sysdeps/s390/fpu/bits/mathinline.h: (__signbitf): Remove. (__signbit): Remove. (__signbitl): Remove * sysdeps/sparc/fpu/bits/mathinline.h (__signbitf): Remove. (__signbit): Remove. (__signbitl): Remove. * sysdeps/tile/bits/mathinline.h: Delete file. * sysdeps/x86/fpu/bits/mathinline.h (__signbitf): Remove. (__signbit): Remove. (__signbitl): Remove.
