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.
