Add patch from upstream [1] to fix a host build with gcc 4.4.x:
  gcc.compile.c++ bin.v2/libs/container/build/gcc-4.4.5/release/threading-multi/pool_resource.o
  libs/container/src/pool_resource.cpp:35: error: declaration of 'typedef class boost::container::pmr::block_slist_base<boost::container::pmr::block_slist_header> boost::container::pmr::pool_data_t::block_slist_base'
  ./boost/container/detail/block_slist.hpp:67: error: changes meaning of 'block_slist_base' from 'class boost::container::pmr::block_slist_base<boost::container::pmr::block_slist_header>'
