powerpc: consolidate rint
This patches consolidates all the powerpc rint{f} implementations on
the generic sysdeps/powerpc/fpu/s_rint{f}.
Checked on powerpc-linux-gnu (built without --with-cpu, with
--with-cpu=power4 and with --with-cpu=power5+ and --disable-multi-arch),
powerpc64-linux-gnu (built without --with-cp and with --with-cpu=power5+
and --disable-multi-arch).
* sysdeps/powerpc/fpu/round_to_integer.h (set_fenv_mode,
round_to_integer_float, round_mode): Add RINT handling.
(reset_fenv_mode): New symbol.
* sysdeps/powerpc/fpu/s_rint.c (__rint): Use generic implementation.
* sysdeps/powerpc/fpu/s_rintf.c (__rintf): Likewise.
* sysdeps/powerpc/powerpc32/fpu/s_rint.S: Remove file.
* sysdeps/powerpc/powerpc32/fpu/s_rintf.S: Likewise.
* sysdeps/powerpc/powerpc64/fpu/s_rint.S: Likewise.
* sysdeps/powerpc/powerpc64/fpu/s_rintf.S: Likewise.
