reopen 1058876 block 1058944 by 1058876 thanksAlas, the fix in openmpi 4.1.6-3 for the include path to the openmpi fortran modules has hardcoded x86_64-linux-gnu
This is preventing builds and tests on other architectures, e.g. rebuilding sundials for the petsc transition.
I think openmpi's debian/tests will also need Depends: pkg-config for the new compile_run_cc_pkgconfig test.
