Remove sysdeps/sparc/sparc32/soft-fp directory.

As per <https://sourceware.org/ml/libc-alpha/2014-10/msg00369.html>,
there should not be separate sysdeps/<arch>/soft-fp directories when
those are used by all configurations that use sysdeps/<arch>, and,
more generally, should not be sysdeps/foo/Implies files pointing to a
subdirectory foo/bar.  This patch eliminates the
sysdeps/sparc/sparc32/soft-fp directory accordingly, merging its
contents into sysdeps/sparc/sparc32.

Tested with build-many-glibcs.py that installed stripped shared
libraries for sparc configurations are unchanged by this patch.
