    tree-optimization/108449 - keep maybe_special_function_p behavior

    When we have a static declaration without definition we diagnose
    that and turn it into an extern declaration.  That can alter
    the outcome of maybe_special_function_p here and there's really
    no point in doing that, so don't.

            PR tree-optimization/108449
            * cgraphunit.cc (check_global_declaration): Do not turn
            undefined statics into externs.

            * gcc.dg/pr108449.c: New testcase.=
