Fix build on pre-v9 32-bit Sparc.
We cannot use fnegd in this code, as fnegd was added in v9.
Only fnegs exists in v8 and earlier.
[BZ #15985]
* sysdeps/sparc/sparc32/fpu/s_fdim.S (__fdim): Do not use fnegd
on pre-v9 cpus, use a fnegs+fmovs sequence instead.
(cherry picked from commit 2216e48645dbd297cdc0f4050fdfc0b52e2a4ab8)
