Remove sysdeps/sparc/sparc64/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/sparc64/soft-fp directory accordingly, merging its
contents into sysdeps/sparc/sparc64.  This completes removing the
unnecessary <arch>/soft-fp sysdeps directories.

sysdeps/sparc/sparc64/soft-fp/e_ilogbl.c is removed rather than moved.
It was not in fact used previously - the ldbl-128 version of
e_ilogbl.c was used instead - and moving it into sysdeps/sparc/sparc64
results in it being used, but causing a build failure because of
FP_DECL_EX declaring an unused variable (as I noted in
<https://sourceware.org/ml/libc-alpha/2013-10/msg00457.html> that file
doesn't appear to use FP_DECL_EX).  Given that the file was previously
unused and so presumably not tested recently, removing it is the safe
way to avoid this patch changing what actually gets built into glibc
(if this file should turn out more efficient than the ldbl-128
e_ilogbl.c, it can always be added back in future with the build
failure fixed).

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