    testsuite, jit, Darwin: Add libSystem to a test.
    
    test-ggc-bugfix.c fails early on Darwin versions using a linker that
    complains if libSystem is not present on user-land link lines.
    
    Add this to fix that specific issue.
    
    gcc/testsuite/ChangeLog:
    
            * jit.dg/test-ggc-bugfix.c: Add libSystem for Darwin.
