Chromium/Mac webkit builds now uses ninja by default too. The bot's
build output is now a little more concise:

On my laptop, full builds are 10% faster and empty builds (the minimum
time you need to wait for a build) are 30x as fast.

If you still need xcodebuild, you can pass --no-ninja to
update-webkit. Please let us know if and why you do this.


ps: Switching Chromium/Windows is blocked on http://crbug.com/169945,
so it probably won't happen soon.
