I don't think that the patch changes the behaviour of "make": it only
changes the behaviour of "make install" and "make test" (and a few
others).

To be honest, I don't know if Makefile knows when a rebuild is needed
and how it works. To run benchmarks, I always rebuild Python from
scratch, even from an empty directory!
