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. * sysdeps/sparc/sparc64/multiarch/sha256-block.c: New file. * sysdeps/sparc/sparc64/multiarch/sha256-crop.S: New file. * sysdeps/sparc/sparc64/multiarch/sha512-block.c: New file. * sysdeps/sparc/sparc64/multiarch/sha512-crop.S: New file. * sysdeps/sparc/sparc32/sparcv9/multiarch/md5-block.c: New file. * sysdeps/sparc/sparc32/sparcv9/multiarch/md5-crop.S: New file. * sysdeps/sparc/sparc32/sparcv9/multiarch/sha256-block.c: New file. * sysdeps/sparc/sparc32/sparcv9/multiarch/sha256-crop.S: New file. * sysdeps/sparc/sparc32/sparcv9/multiarch/sha512-block.c: New file. * sysdeps/sparc/sparc32/sparcv9/multiarch/sha512-crop.S: New file.
