Since we intend to provide cross version compatibility
between versions with the same major and minor, use
MAJOR.MINOR.0 instead of orte_version_string
(e.g. MAJOR.MINOR.RELEASEGREEK).
Open MPI 4.0.0 has already been released, so in order to make
it compatible with future 4.0.x releases, we have to use 4.0.0
as the version string, that is why we use MAJOR.MINOR.0 instead
of MAJOR.MINOR
