Both gcc and dpkg playing with PIE just increased the number of bugs
without bringing any benefit.

I fixed many PIE related issues in packages when the gcc change was.

And now we got a new batch of FTBFS bugs for cases where the
dpkg specs change broke packages using "hardening=+all,-pie".

Please do the following:
1. discuss with porters whether PIE is working on their architecture
2. gcc and dpkg maintainers have to agree which package enables PIE
