    gnu: hdf5-parallel-openmpi: Really enable parallel build.
    
    This fix ensures that the H5_HAVE_PARALLEL identifier is correctly set
    in the file H5pubconf.h.
    
    * gnu/packages/maths.scm (hdf5-parallel-openmpi)[arguments]: Add
    the "--enable-parallel" flag to the list of configure flags.  Remove
    the incompatible "--enable-cxx" flag.  Add 'mpi-setup' phase.
