Pex 1.4.1 installs windows eggs on linux/OSX

[mcouthon]

I've installed pex with pip install pex, then I created a minimal setup.py file in a folder named test that looks like this:

from setuptools import setup

setup(
    name='test',
    version='0.1',
    install_requires=[
        'netifaces==0.10.6'
    ]
)

And then I ran pex ./test -o /tmp/pex_out -vv and got this:

Saving PEX file to /tmp/pex_out

As you can see, although I'm running on OSX, the netifaces egg that's fetched is a Windows one (https://files.pythonhosted.org/packages/05/00/c719457bcb8f14f9a7b9244c3c5e203c40d041a364cf784cf554aaef8129/netifaces-0.10.6-py2.7-win32.egg).

This works on pex==1.3.2
