* configure.ac: Don't change the gnulib default of 'no' for

+  md5sum can use libcrypto hash routines where allowed to potentially
+  get better performance through using more system specific logic.
   sha1sum for example has improved throughput by 40% on an i3-2310M.
   This also affects sha1sum, sha224sum, sha256sum, sha384sum and sha512sum.
