The outmost shell loop got replaced with a (hidden) bunch
of targets -- it's somewhat controversial as the inner loops
are still there (but at least don't wrap around my SXGA+).

Full targetization might be beneficial in terms of parallelism
achievable *but* that would ruin git history being generated,
and building a distro configuration takes a few seconds at most.
