If you define BOOST_THREAD_DONT_USE_CHRONO, I don't see why you need

boost/chrono/system_clocks.hpp

Well I think I see what is not working. Where are you defining 
BOOST_THREAD_DONT_USE_CHRONO? You need to do it the command line and 
requested to don't build Boost.Chrono and a build without Boost.Chrono.

bjam define=BOOST_THREAD_DONT_USE_CHRONO --without-chrono
