The attached patch fixes issues with Python's Makefile, which manifest when
doing parallel builds. The Makefile invoked make recursively for some
targets. This caused some files (which were depended upon by multiple targets)

No change for 3.x (unless something changed on the pip side that I'm not

As Donald notes, this was explicitly covered in the PEP: the onus is on the
