    gnu: openmpi: Remove references to compiler pathnames in "_info" programs.
    
    This reduces the closure greatly, but note that the Fortran .mod files are
    gfortran version-specific, so there should probably be development packages
    for each incompatible version.  (The runtime is supposed to be more-or-less
    version-independent unless the libgfortran soname changes.)  There may still
    be a case for a separate runtime output.
    
    * gnu/packages/mpi.scm (openmpi)[arguments]: Add "remove-absolute" phase.
