Bringing up this OpenMP endian bug fix again.  While this PR is over a year old, the problem exists just the same in current mainline.   One visible symptom caused by the bug is that the `barrier/omp_barrier.c` just hangs forever on some big-endian machines (it somewhat depends on the NUMA topology).  Unfortunately, one of the systems where it just about *always* hangs is the server we will use as new host of the SystemZ build bots.   Therefore, addressing this bug is becoming more important now -  I'd appreciate a review.  Thanks!
