run_par_warn_test tests fails

[opoplawski]

I'm testing updating the Fedora netcdf package to 4.9.3-rc2 and getting the following test failure:

===============================================

Testing MPI parallel I/O with various other mode flags...

diff: ref_tmp_tst_warn_out.txt: No such file or directory
FAIL run_par_warn_test.sh (exit status: 2)

This looks like another issue with out of tree builds as that file does exist here: netcdf-c-4.9.3-rc2/nc_test4/ref_tmp_tst_warn_out.txt but not in the netcdf-c-4.9.3-rc2/mpich/nc_test4 directory where the tests are being run.
