You can add that line from angstrom-core-tweaks into your local.conf,
but it depends on distro maintainer if he wants to support different
DISTROs in distro layer.

In other words, everything in distro layer can usually assume correct
distro configuration, when you're using some recipes from distro layer
with your own distro or distroless config then you're on your own
unsupported combination.
