The cl_amd_media_ops extension isn't listed in clinfo for the working or
non working beignet case.
This is the specific source generating that error:
The overall source isn't currently setup to build in FreeBSD, that is
what I'm working on.
I noticed it's wrapped in a test to check for the extension before using
it. Not sure if that is the correct way or not.
Tried building patched beignet with LLVM 3.9, different error message,
fails an internal consistency check in the code.
