Make: handle warning files while building in a directory

The dependency on the warning files breaks when we are building in a
directory *and* the files already exist from being shipped with the
distribution tarballs. The make VPATH simply isn't sophisticated
enough to deal with it, so let the C compiler handle it by #including
the generated file from a dummy C file.
