build fails on archlinux

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

Hi, I encountered build error on archlinux, possibly because of my gcc and ld version.

Presumably coming from https://github.com/google/python-subprocess32/blob/master/_posixsubprocess.c#L3 and the stuff we do to define things that aren't supposed to have been defined in CPython 2.7's pyconfig.h.

Rather than try to untangle this myself as if it doesn't reproduce on a Debian based system I'm not going to try to recreate it... I expect to create a final manylinux2014 (or whatever that is finally called) binary wheel for subprocess32 before the end of the year which should prevent most x86_64 people from needing to compile it on their own.

I just uploaded a manylinux2014 wheel for long term posterity. This project is otherwise closed as python 2 is EOL.
