Add support for sparc cryptographic hash opcodes.

	* crypt/Makefile: Move test targets after toplevel Rules
	inclusion.  Grab any necessary sysdep routines when linking.
	* crypt/md5.c (md5_process_block): Remove define, we will always
	name it __md5_process_block.
	(md5_finish_ctx): Update md5_process_block call.
	(md5_stream): Likewise.
	(md5_process_bytes): Likewise.
	(md5_process_block): Rename to __md5_process_block and move to ...
	* crypt/md5-block.c: ... here.
	* crypt/sha256.c (sha256_process_block): Move to ...
	* crypt/sha256-block.c: ... here.
	* crypt/sha512.c (sha512_process_block): Move to ...
	* crypt/sha512-block.c: ... here.
	* locale/Makefile (CFLAGS-md5.c): Define to add crypt/ to include
	path.
	* sysdeps/sparc/sparc-ifunc.c (sparc_libc_ifunc): Define.
	* sysdeps/sparc/sparc64/multiarch/Makefile
	(libcrypt-sysdep_routines): Add crypto assembler sysdeps when in
	crypt subdir.
	(localedef-aux): Add md5 crypto assembler when in locale subdir.
	* sysdeps/sparc/sparc32/sparcv9/multiarch/Makefile: Mirror sparc64
	multiarch changes.
	* sysdeps/sparc/sparc64/multiarch/md5-block.c: New file.
	* sysdeps/sparc/sparc64/multiarch/md5-crop.S: New file.
