Fix powerpc32 llrint, llrintf bad exceptions (bug 16422).
The versions of llrint and llrintf for older powerpc32 processors
convert the results of __rint / __rintf to long long int, resulting in
spurious exceptions from such casts in certain cases.  This patch
makes glibc work around the problems with the libgcc conversions when
the compiler used to build glibc doesn't use the fctidz instruction
for them.

Tested for powerpc.

	[BZ #16422]
	* sysdeps/powerpc/powerpc32/fpu/configure.ac (libc_cv_ppc_fctidz):
	New configure test.
	* sysdeps/powerpc/powerpc32/fpu/configure: Regenerated.
	* config.h.in [_LIBC] (HAVE_PPC_FCTIDZ): New macro.
	* sysdeps/powerpc/powerpc32/fpu/s_llrint.c: Include <limits.h>,
	<math_private.h> and <stdint.h>.
	(__llrint): Avoid conversions to long long int where those might
	raise spurious exceptions.
	* sysdeps/powerpc/powerpc32/fpu/s_llrintf.c: Include
	<math_private.h> and <stdint.h>.
	(__llrintf): Avoid conversions to long long int where those might
	raise spurious exceptions.
