Intel LLVM does not like -lgfortran linker

To report a non-security related issue, please provide:

the version of the software with which you are encountering an issue 4.6.1
environmental information (i.e. Operating System, compiler info, java version, python version, etc.) ubuntu 22.04.4 HDF5_Version=1.14.4 HDF5_Sub_Version=2 Zlib_Version=1.3.1 Netcdf_C_Version=4.9.2 Netcdf_Fortran_Version=4.6.1 Mpich_Version=4.2.1 Libpng_Version=1.6.39 Jasper_Version=1.900.1 Pnetcdf_Version=1.13.0
a description of the issue with the steps needed to reproduce it When compilling netcdf-fortran && netcdf-c with the -lgfortran flag it raises an error saying unable to compile using intel llvm compilers. When using the intel classic compilers it did not have this issue. Which is intel compilers before 2023

I would think that the gnu compilers wouldn't cause a problem because the -lgcc linker can be in the CFLAGS command and it doesn't cause it to break. Only the -lgfortran.

Some relevant code that I am using:

    cd "${WRF_FOLDER}"/Downloads
    tar -xzvf v$Netcdf_C_Version.tar.gz
    cd netcdf-c-$Netcdf_C_Version/

    # these variables need to be set for the NetCDF-C install to work
    export CPPFLAGS=-I$DIR/grib2/include
    export LDFLAGS=-L$DIR/grib2/lib
    export LIBS="-lhdf5_hl -lhdf5 -lz -lcurl -lgcc -lm -ldl -lpnetcdf"
    autoreconf -i -f 2>&1 | tee autoreconf.log

    # other libraries below need these variables to be set
    export PATH=$DIR/NETCDF/bin:$PATH
    export NETCDF=$DIR/NETCDF

    echo " "

@WardF

Here's my issue that I opened with all the log files.

@edhartnett @WardF

not sure why the linker for gfortran doesn't work. Seems to affect all versions of netcdf including cxx. Maybe it's an intel llvm problem?

Thanks for your patience; the netCDF-C release has been demanding a lot of my time. Let me review this.

that's okay take your time, just trying to help @WardF
