#6784: missing weak symbol support

The runtime loader doesn't support (defined) weak symbols yet. It is
[http://refspecs.freestandards.org/cxxabi-1.83.html#rtti implicitly
required by the (Itanium) C++ ABI], though:
"It is intended that two type_info pointers point to equivalent type
descriptions if and only if the pointers are equal. An implementation must
satisfy this constraint, e.g. by using symbol preemption, COMDAT sections,
or other mechanisms."
