Ah, we have something funny going on, or at least not clear enough.  We
need and want -E here as that causes us to build with -Werror and so
warnings become errors and the build fails.  We still ignore warnings
such as "go convert X to DM" (which is its own issue to deal with) and
also dtc warnings (which is its own issue to deal with).
