sparc: Remove optimize md5, sha256, and sha512
The libcrypt was maked to be phase out on 2.38, and a better project already exist that provide both compatibility and better API (libxcrypt). The sparc optimizations add the burden to extra build-many-glibcs.py configurations. Checked on sparc64 and sparcv9. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
