[swift-dev] Failure: Swift master branch build failing on x86 (Ubuntu 16.04).

[Slava Pestov]

Hi Atul,

The master branch is tested in CI, so any build failures are likely due to configuration problems on your end. While testing the swift-4.0-branch would provide an interesting data point, I would not expect it to work if building master fails.
