libcoprthr_opencl: OpenCL specific compiler flags interupt build and crash in elfcl routines

[sctincman]

If an application passes in OpenCL specific compiler flags when using libcoprthr_opencl (such as "-cl-strict-aliasing" or any of the ones listed here https://www.khronos.org/registry/cl/sdk/1.0/docs/man/xhtml/clBuildProgram.html), these will be passed straight to gcc/g++, which will throw an "unrecognized option" error and not output the needed program.

This seems to result in an empty elf file that causes elfcl_write to signal SIGABRT from malloc (at least from my cursory backtraces and stracing).

Thanks. Fortunately there is a place where flags are blocked. I believe this can be addressed at that point.
