Bug#188943: [Bug c++/10891] code using dynamic_cast causes segfaults when -fno-rtti is used

protection against dynamic_cast<> with -fno-rtti is too eager

Here's a test that NEVER instantiates the template, but if compiled with

     g++ -fno-rtti

will (un)happily complain.

Ideally, unless I call the templated function derived<T>::upcast() from a
compilation unit that has -fno-rtti specified, I really don't think I should
get an error
