    testsuite, Darwin: Allow for an undefined symbol [PR114036].
    
    Darwin's linker defaults to requiring all symbols to be defined at
    static link time (unless specifically noted or dynamic lookuo is
    enabled).
    
    For this test, we just need to note that the symbol is expected to
    be undefined.

            on Darwin link lines.
