[boost] patch to build boost on dragonflybsd

the attached patch makes it possible to build boost on dragonflybsd with 
gcc3.4.

the change in boost/python/detail/config.hpp is necessary as dfly doesn't 
provide the gcc-patched headers that "fix" offsetof().

if defined(freebsd)&&!defined(dragonfly) is in there as dfly sometimes defines 
both of them.

after this patch, everything except boost::serialize (which complains about 
lack of wchar_t) should build.
