[Aakash Jain]

We should add a build step in ews-build to print bot configuration (e.g.: Xcode version). This would help in debugging failures.

These commands will not work for any Windows EWS bots. We should probably do a platform check, or at least put in a #FIXME to indicate any non Mac/unix work needed.
(since halt/flunk/warn on failure is False, this won't break anything on those platforms...but it would be nice to do the right thing pending OS.
