I wrote a blog about this and got flamed a lot for even suggesting to remove 
the option of symbol interposing. But the fact of life remains that only 
specially-crafted symbols can be safely interposed in libraries. libdbus-1 
definitely does not take care of that and will not accept bug reports if 
interposition of one of its symbols does not work.

We currently link Qt 5 with -Bsymbolic-functions by requiring all applications 
to be compiled with -fPIE or -fPIC. That's currently the only way to avoid 
copy relocations and the executable "stealing" the official entry address for 
public functions it uses. That requirement actually enables us to use -
Bsymbolic if we wanted to or even protected visibility (which I use locally).
