ocrad 0.22: Patch for libc++ in Mavericks

Updated ocrad to 0.22 and added minor patch that fixes compilation with libc++. This has been reported to the ocrad mailing list:

http://lists.gnu.org/archive/html/bug-ocrad/2013-11/msg00000.html

Removed configure options `--disable-debug` and `--disable-dependency-tracking` as they are not recognised by the configure script.

Added simple test to check `ocrad` command line tool exists.

Closes #24879.
