I think calling -Bsymbolic-functions a broken concept is harsh, given that it 
makes a lot of sense - doesn't it?

The fact that it breaks when comparing addresses of functions sucks, but IMHO 
compiling PIC/PIE is still better than going back to all those unecessary 
relocations just because somebody _might_ interpose a symbol of the public API 
of the library.
