Correction/Clarification: where I wrote PIE I meant "relocateable executable", as enabled with -pie during linking (which has no effect on generated code). I did not consider the case of -fpie, which instead affects code generation. And the detection whether we need to add -fpie (if I remember correctly we have such, but I didn't check the code) might be reused as a heuristic whether we need to enable PIC as well.
