gdb: Remove support for SH-5/SH64

Browse Source 
Since bfd dropped support for SH-5, there's no point in keeping it in
GDB either.

This restores --enable-targets=all builds.

gdb/ChangeLog:
2018-04-16  Pedro Alves  <palves@redhat.com>

	* MAINTAINERS (sh): Remove.
	* Makefile.in (ALL_TARGET_OBS): Remove sh64-tdep.o.
	(HFILES_NO_SRCDIR): Remove sh64-tdep.h.
	(ALLDEPFILES): Remove sh64-tdep.c.
	* NEWS: Mentions that support for SH-5/SH64 is removed.
	* configure.tgt (sh*-*-linux*): Remove reference to sh64-tdep.o.
	(sh*-*-openbsd*): Ditto.
	(sh64-*-elf*): Remove.
	(sh*): Remove.
