I suggest using -fPIC, because then the shared libraries would be
usable in shared (PIC) libraries libraries, too.

This in many cases also simplify debian/rules. I also suggested
changing the policy #837478.

In most of the cases this would be sufficient, but at the time I filed the
bugs the default was -no-pie, thus it was not an option.

I'm OK with performing binnmu-s and decreasing the severity of the 'solved'
bugs to wishlist.
