As I said, the code in question uses dlsym, so nothing interesting happens,
multiple symbols in different shared objects have different addresses.

If you're worried about symbolic references from inside shared objects (even
though we have no indication that this is a problem in the real world, it has
always worked like this) then at the very least they should be made protected
so that they are bound internally, but also exported.  The latter part is
what is important for existing code.
