The OpenMP flags do not definitively identify that OpenMP is used. In
particular, IBM XL interprets Cray's option -h omp as being equivalent to
-soname omp, then silently ignores the Open MP pragmas. We can perhaps
fix this instance by moving -qsmp up in the list, but we may eventually
need to

Perhaps the 'empty' flag check should be at the begining of the list..
[we do have other places in configure where we fix the order in which
flags are checked - due to similar conflicts between compilers]

No, because most compilers ignore the pragmas when no options are given. I
do not know of any portable way, short of running code, to determine
