Whilst I will admit I've not extensively tested it, I think that should
be possible to override things as this only gets validated after all
the layer.conf files are pulled in. It would need to be from the
distro's layer.conf though, or a layer.conf in the build directory as
local.conf comes in much later. Basically its possible but not easy,
which I think is probably the right thing to do here.
