Tools are not built to match Pants minimum supported platforms

[jsirois]

For example, Pants builds OSX wheels against OSX 10.11 (see https://github.com/pantsbuild/pants/blob/master/.travis.yml#L92 and https://docs.travis-ci.com/user/reference/osx/#OS-X-Version), but we see:

We should probably use a CI job to build any binaries not on S3 using the same minimum images we use in pantsbuild/pants.

This is a long standing problem with the way we build binaries and you just got unlucky. I'm going to tackle this tomorrow but likely lean on you for review.
