I haven't looked to see for sure what the difference between the two
would be. But if ompi_info provides the information that we need, then
we can use it. Otherwise then we should try to parse config.log if it
is available.

If we are doing an MPI Install and the build fails (due to maybe an
enabled feature) then we will have to depend upon parsing config.log
to see exactly which fields are available since ompi_info will not be
available to us at this point.
