    gnu: hdf5: Add output for fortran interface.
    
    * gnu/packages/maths.scm (hdf5) [native-inputs]: Add gfortran.
      [outputs]: Add "fortran".
      [arguments]: Enable Fortran compilation; add "/lib" directory of the 
fortran
      output to the runpath of the Fortran libs; add a 'split phase to move
      all Fortran-related files to the the Fortran output store location.
