Comment (by mascguy):

 I'm unable to reproduce this failure locally on 10.11, building with Xcode
 7.3.1.

 Of note, both the reporter - as well as our 10.11 buildbot - are utilizing
 Xcode 8.2.1. However, the latter includes the 10.12 SDK, which appears to
 be the culprit.

 Currently pondering what the best way to fix this is. But in the interim,
 if you switch to Xcode 7.3.1 - which I'd strongly recommend anyway, unless
 you have any ports that require a 10.12 SDK - that should solve the issue.
