Rebuilding packages to increase Stretch's PIE coverage

[Bálint Réczey <balint@balintreczey.hu>]

Dear Release Team,

GCC uses PIE by default in unstable and testing but most packages
which haven't been rebuilt since the transition still ship unprotected
binaries [1].

If the Team agrees I suggest rebuilding the packages which would
benefit from a rebuild. In case this gets a green light I would
volunteer to perform a test rebuild for each package to see if the
lintian warning goes away.

Ideally #848129 would be fixed before the rebuild but it seems unlikely
that it would move forward without Release Team weighing in. I support
Adrian's suggestion about removing all PIE support from dpkg.

Cheers,
Balint
