Well, that works perfectly find from scratch. FWIW I just run the
incremental build bot to try and isolate the cases where our
dependencies don't work on rebuilds. It doesn't mail anyone else apart
from me, but does raise the question of having dependencies on the
makefiles themselves I suppose. Probably an unpopular idea if everyone's
tree is effectively auto make cleaned if someone adds a line to the
toplevel makefiles.
