It's just a set of rules to make the main makefile recurse into
subdirectories if any files in the subdirs have changed.
Unconditionally recursing into them is also possible but would make
performance extremely bad in the common case where nothing has
changed.

Of course I'd be happiest if we could eliminate recursive make
altogether...
