Remove sysdeps/sh/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/sh/soft-fp directory accordingly, merging its contents into sysdeps/sh. Tested with build-many-glibcs.py that installed stripped shared libraries for sh configurations are unchanged by this patch. * sysdeps/sh/Implies: Remove sh/soft-fp. * sysdeps/sh/soft-fp/sfp-machine.h: Move to .... * sysdeps/sh/sfp-machine.h: ... here.
