The feature I require does not yet exist. I need movable std streams 
which MSVC supports since 2015 but 2013 does support most (many) C++11 
features already. So checking other features is not reliable.
I don't know enough about B2 to implement such thing myself. It seems to 
be Boost.Config providing those but most checks rely on Boost macros or 
std feature tests. There is neither for this.
