gnu/c++03 -> gnu/c++11 was special as there was libstdc++ library ABI break.

As far as I am aware gcc6 changes the default _standard_ version to
gnu++14, however it remains binary compatible with gnu/c++11 libstdc++
ABI.

In other words, please do not assume that we need to bump ABI across
the board the way we did when migrating to libstdc++ 11 abi.

I will do more checking, but my understanding is that current boost
should be fit for purpose for either gnu++11 or gnu++14 standard
builds with c++11 libstdc++ ABI. Debian no longer supports libstdc++
c++03 abi.
