We include a file containing cached values for Fortran tests that are
performed at the configure step. These tests fail when cross-compiling
and this is known upstream. See:
https://www.open-mpi.org/community/lists/users/2013/01/21186.php
In that thread the upstream maintainer admits that "cross compiling
OpenMPI is a known issue" and the way to workaround this is to
"pre-populate configure's answers to the Fortran tests (so that it
doesn't actually have to run anything)"
