  #   1. An attempt to stop anything going in %{prefix}/lib64 (which doesn't
  #      fully work; we will need to hobble the multilib configuration in
  #      config/i386/t-linux64 if we really want to kill /lib64).
  #   2. Avoid having more than one copy of ZLib in use on the system
  #   3. Multilib does not make sense in Baserock.
