commit a3c279e2479af2cedff13d2437bda2ae31468a2c
Author: Drew Parsons <dparsons at debian.org>

    remove configure option --with-mpi-dir
    
    MPI compilers mpicc, etc. are found automatically during
    TEST checkCCompiler, checkFortranCompiler, checkCxxCompiler in
    config/BuildSystem/config/setCompilers.py.
    
    Note in particular the warning from TEST checkMPICompilerOverride:
      Check if --with-mpi-dir is used along with CC CXX or FC compiler options.
        This usually prevents mpi compilers from being used - so issue a warning
    
    In v3.8 this warning is given substance by upstream commit a98758b
    (2017-02-15), which drops mpi compilers if the bin subdir is missing
    from the MPI dir.
    
    We were using --with-mpi-dir=/usr/lib/x86_64-linux-gnu/openmpi
    and indeed that mpi dir has no bin subdir.
    
    So if mpi compilers are already found, then --with-mpi-dir is not
    required. It prevents configuration if we do use. So remove it.
