boost: Add patch to avoid undefined references to boost::atomic::lockpool::get_lock_for()
Boost::thread uses functions from boost::atomic but doesn't actually
link with libboost_atomic. This works fine on platforms where
BOOST_ATOMIC_FLAG_LOCK_FREE is true but will lead to undefined
symbol references otherwise. Fix this by applying a patch from
the upstream bug tracker to add the missing library linkage.
