Do compile commands (shown with "bjam -n") contain all of the above settings? 
If yes, then I suspect something is wrong with thread detection for 
cross-compiling. In fact, I can't figure out where "requires_threads.hpp" is 
included from.

If some flags are missing, this could be a bug in Boost.Build.
