The ubi-utils/src/ subdir is tossed as it just complicates things for no real gain. The top level clean is replaced with a `find -delete` on objects, so it might prune more than necessary, but many projects now do this sort of thing and no one complained there. A "mkdep" helper generates the actual rule, and the variables are used with "foreach" to expand these automatically. While we're gutting things, also through in kbuild style output while building to make things more legible.
