Yes it's thread safe as long as GCC and libstdc++ are (which they should be 
on your platform).  At some point Boost.Build reduced the number of build 
variants on Linux so we basically only build thread safe release versions.

PS You can always check this in your code with a:

#include <boost/config.hpp>

#ifndef BOOST_HAS_THREADS
#error "Ooops"
#endif
