  configure.ac, Makefile.am: Allow setting of OpenCL location 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. Signed-off-by: Tom Rini <trini@kernel.crashing.org>
