This PR makes Boost.Config depend on all the related Boost libraries 
creating a whole cycle and modularity will be broken.

It would suggest to have some kind of Boost.Std library with different 
versions c++11/c++14 and why not TSs.

However the concerned libraries couldn't use this library without adding 
cycles :(

Having a sub-library for each file Boost.Std/Regex would make it 
possible for a Boost library to use these sub-libraries without adding 
cycles.

An alternative is to add these files in the concerned libraries, e.g. 
boost/regex/std/regex.hpp
