SuiteSparse doesn't use Fortran source and after bug 208120 there's no need to worry about RPATH for libgcc_s.

Testing postponed until the next update. The change provides little value on its own.

$ grep  -i fortran ./SuiteSparse_config/SuiteSparse_config.mk
        BLAS = -lrefblas -lgfortran -lstdc++
            # use the Intel ifort compiler for Fortran codes
    # standard Fortran LAPACK along with OpenBLAS to obtain very good
    #   make BLAS='-lacml -lgfortran'
    # Fortran compiler (not required for 'make' or 'make library')
    # A Fortran compiler is optional.  Only required for the optional Fortran
    F77 ?= gfortran
        ## BLAS = -lrefblas -lgfortran
        @echo 'Fortran compiler:         F77=            ' '$(F77)'
        @echo 'Fortran flags:            F77FLAGS=       ' '$(F77FLAGS)'

So it seems that Fortran is optional:

    # A Fortran compiler is optional.  Only required for the optional Fortran
    # interfaces to AMD and UMFPACK.  Not needed by 'make' or 'make install'
 
Does anyone need these interfaces?

Note: if we adopt the proposed patch, maintainership should be dropped from fortran mailing list.
