This patches consolidates all the powerpc {l}lround{f} implementations
on the generic sysdeps/powerpc/fpu/s_{l}lround{f}.c.

The IFUNC support is also moved only to powerpc64 only, since for
powerpc64le generic implementation resulting in optimized code.

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/powerpc64/be/fpu/multiarch/Makefile
	(libm-sysdep_routines): Add s_llround-power8, s_llround-power6x,
	s_llround-power5+, s_llround-ppc64, and s_llroundf-ppc64.

I found just a small problem in this patch (see below).

Thanks, again.

For reference, again, a powerpc64 build produces:

The removal of the two lines above is likely unintentional and wrong.

Looks good to me with that fixed.  Thanks.

+      "roundf to Nearest" as "Choose the best approximation. In case of a
+      tie, choose the one that is even (least significant bit o).".
+      So we can't use the PowerPC "round to Nearest" mode. Instead we set
+      "round toward Zero" mode and round by adding +-0.5 before rounding
+      to the integer value.
+
+      It is necessary to detect when x is (+-)0x1.fffffffffffffp-2
+      because adding +-0.5 in this case will cause an erroneous shift,
+      carry and round.  We simply return 0 if 0.5 > x > -0.5.  Likewise
+      if x is and odd number between +-(2^23 and 2^24-1) a shift and
+      carry will erroneously round if biased with +-0.5.  Therefore if x
+      is greater/less than +-2^23 we don't need to bias the number with
+      +-0.5.  */
