Was this a historical issue on the buildds e.g. still using GCC 4.8 with 
a newer hardening-wrapper?  I can't reproduce in current unstable.

I assume that some other package is providing the 
-fstack-protector-strong argument and that GCC 4.8 doesn't support it. 
But I'm not sure that it's an schroot problem unless there is some 
versioned build dependency that needs correcting?  Or is it a dependency 
problem is some part of build-essential?
