Just to elaborate: as the error message implies, this error message was put there specifically to ensure that the Fortran compiler works before continuing any further. If the Fortran compiler is busted, configure exits with this help message.
You can either fix your Fortran compiler, or use --disable-mpi-fortran to disable all Fortran support from Open MPI (and therefore this "test whether the Fortran compiler works" test will be skipped). Here's the specific log section showing the failure: ----- configure:32389: checking if Fortran compiler works configure:32418: gfortran -o conftest conftest.f >&5 configure:32418: $? = 0 configure:32418: ./conftest ./conftest: error while loading shared libraries: libquadmath.so.0: wrong ELF class: ELFCLASS32 configure:32418: $? = 127 configure: program exited with status 127 configure: failed program was: | program main | | end configure:32434: result: no configure:32448: error: Could not run a simple Fortran program.
