Even with a non-recursive make, the incremental builds can only be
reliable if you are modifying existing files (or possibly adding new
files that the Makefile will wildcard). They aren't always reliable in
cases where you rename or remove files, modify the Makefiles
themselves, or forget to list certain dependencies.
