    libcc1: Fix up libcc1 configure [PR98330]
    
    Either we should write test x$darwin_dynamic_lookup = xyes
    or we should make sure the variable is always defined to non-empty string.

            * configure.ac: Set darwin_dynamic_lookup=no instead to empty
            string.
            * configure: Regenerated.
