 ..and if you try it with `deplibs_check_method=test_compile', then
you will note spurious errors during linking.  This mostly trivial
patch fixes them.  OK to apply?

        * libltdl/config/ltmain.m4sh (func_mode_link) < test_compile >:
        Fix a couple of instances where `test .. -ne ..' would possibly
        compare non-numbers.  Clean up a bit.
