Remove some math_private.h libc_fe* overrides.
math_private.h headers for configurations lacking support for floating-point exceptions and rounding modes define various libc_fe* macros to override the default versions with ones that discard any exception or rounding mode arguments. Three of the four macros defined in these headers are no longer needed there: those macros are only used in fma implementations that are not used for such configurations, now all those configurations properly use soft-fp fma implementations instead. (Effectively, those macros were a workaround to allow glibc to build in the absence of a proper fma implementation for this case - now there is such an implementation, there is no need to support building the wrong implementation for those configurations.) Thus, this patch removes the unnecessary macros. Tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/m68k/coldfire/nofpu/math_private.h (libc_fesetround): Remove macro. (libc_fetestexcept): Likewise. (libc_feupdateenv_test): Likewise. * sysdeps/microblaze/math_private.h (libc_fesetround): Likewise. (libc_fetestexcept): Likewise. (libc_feupdateenv_test): Likewise. * sysdeps/nios2/math_private.h (libc_fesetround): Likewise. (libc_fetestexcept): Likewise. (libc_feupdateenv_test): Likewise. * sysdeps/tile/math_private.h (libc_fesetround): Likewise. (libc_fetestexcept): Likewise. (libc_feupdateenv_test): Likewise.
