      I'm not familiar how the llvm's cmake build machinery handles a
parallel make check. Since the existing openmp testsuite wants to run
on all available processor cores, you probably want to structure the
openmp cmake files such that the make check in openmp is the only make
check in llvm running at the time (to prevent competition for the
processor cores).
