Hi! yesterday I received a [bug] report asking Qt to not requiring apps using
it to pass -fPIC (actually to let the app use -fPIE) due to hardening reasons.
Now as we are using -reduce-relocations and gcc5 this is currently not
possible at least until gcc's upstreams decide to add this as a [feature].
Now I would like to know if someone can enlight me as to where are the
drawbacks of both options: reducing rellocations and not enabling "hardening"
or the contrary, not reducing rellocations and enabling hardening.
Of course I happily pointers to stuff to read, I'm just lost with this one.

[feature] <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65886#c30>
Thanks in advance, Lisandro.
