    x86-64: Test protected function pointers

    On x86-64, function pointers in executable for external funtions may be
    resolved to their PLT entries in executable.  If it happens, function
    pointers of protected funtions in shared libraries must be resolved to
    the PLT entries in executable, not addresses of protected funtions in
    shared libraries.
