Subject: [PATCH] Allow all wheels from PyPI

It's unlikely that we're going to need any changes in pip itself
to support linux enabled wheels except for maybe a more specific
platform tag. If a more specific platform tag is needed then older
pip's won't install that anyways. This should allow experimentation
with some possible solutions to linux enabled wheels.
