I see, this workflow is the exact reverse of mine:
I do as much as possible in a single tree so I
rely on the makefile dependencies to be correct
to rebuild the right things.
You don't need so many dependencies: just enough
to pull the right bits from the cache.
I can see how any patches correcting in-place rebuilds
won't scratch any of your itches.
