configure.ac, Makefile.am: Allow setting of OpenCL location

Browse Source 
Add two new configure flags, --with-opencl-libdir and --with-opencl-inc
to specify where OpenCL headers and libraries exist.  This now adds
a test for the OpenCL header file and makes not finding the library
or headers a fatal error.
