Full failure report

I'm getting these failures on AArch64 in 6.0.0-rc2:

Failing Tests (6):
    libomp :: ompt/misc/control_tool.c
    libomp :: ompt/synchronization/flush.c
    libomp :: ompt/synchronization/master.c
    libomp :: ompt/synchronization/taskwait.c
    libomp :: ompt/synchronization/test_lock.c
    libomp :: ompt/synchronization/test_nest_lock_parallel.c

They all look something like this:
******************** TEST 'libomp ::
ompt/synchronization/test_nest_lock_parallel.c' FAILED ********************
