    Avoid crash when global symbol table is empty with -fdump-fortran-global.

    This just avoids a crash with -fdump-fortran-global when the
    global symbol table is empty.  This is strictly a developer's
    option, no user impact.

            * dump-parse-tree.c (gfc_dump_global_symbols):  If the symroot is
            empty, just output "empty".
