[Beignet] Weird clinfo ouput @ FreeBSD-11.0/Intel GPU

That looks like the "no __local on Haswell" issue (Linux fixed this in 4.2,
but FreeBSD might not have): try

OCL_IGNORE_SELF_TEST=1 clinfo

If you compiled Beignet yourself, also try running the test suite:
make utest
cd utests
. setenv.sh
./utest_run

If it is that, I'd expect most but not all of them to pass.
