by default all calls from library to public/global functions exported
by this library go through PLT. in such case you can override global
symbol (e.g. with LD_PRELOAD=myhack.so which exports eq. symbol).
with -Bsymbolic-functions such calls will be bound directly
and all happy library hacking isn't so easy.
