Remove sysdeps/alpha/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/alpha/soft-fp directory accordingly, merging its contents
into sysdeps/alpha.

Tested with build-many-glibcs.py that installed stripped shared
libraries for alpha-linux-gnu are unchanged by this patch.
