Can you point me at the recipe you're using this in? I suspect we should
just remove the map_dependencies() pieces from this class entirely and
handle dependency issues with the override manually. I think at this
point all the BBCLASSEXTEND is going to give you is the removal of the
need to add a separate .bb file with "inherit cross" in it and enable an
override for your to use. I'm not sure we can write generic dependency
mapping code that would work for -cross.
