Deviating from upstream requirement for compiler is a riskier choice for
freeze.

Documentation to require c++11 is to shove -std=gnu++11 as a flag,
upstream could be doing it themselves.

This was necesssary because libraries made headers which require C++11 to
use, and further downstream packages did not adjust flags yet.
