With recursive make, you can type make in a subdirectory and get just
that directory, and I agree that's useful, but when you are at the top
directory you cannot make specific targets in the recursive makefiles.

One makefile basically ignores directories, but recursive makefiles
artificially hide their contents. Personally, I have had much better
luck with a single makefile than with recursive makefiles, but a fair
amount probably depends on personal style.
