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.
