Mikhail Novosyolov b021593695 Enable -fstack-protector(-strong) 
It is a rather low cost (in performance terms) additional security
and is useful for e.g. certified systems.
As the performance difference is not expected to be even measurable well enough,
let's enable is everywhere. We do not need to support GCC 5 any more.
