GEODE-2733: Fix integration test errors on xcode 8.3.3


> Crash during initialization using Xcode 8.3
> -------------------------------------------

>                 Key: GEODE-2733
>                 URL: https://issues.apache.org/jira/browse/GEODE-2733
>             Project: Geode
>          Issue Type: Bug
>          Components: native client
>            Reporter: Michael Dodge
>            Priority: Minor
>
> Circa 27 March 2017, Apple released the macOS 10.12.4 and Xcode 8.3 updates. 
> After applying those updates, all native client executables (e.g., unit 
> tests, integration tests, quickstarts) crashes with a SIGSEGV/EXC_BAD_ACCESS 
> with pthread_mutex_lock() which is part of the initialization of the ACE 
> libraries. We don't know whether it's caused by an incompatibility between 
> ACE and the 10.12.4 runtimes (e.g., a struct has changed in size) or if it's 
> an actual bug in the runtimes. Mike Martell found a bug that has already been 
> filed with Apple about Emacs crashing with pthread-related problems after 
> this update, so our current theory is that there's a problem in the pthreads 
> library from Apple.
> UPDATE: Dave Barnes installed just macOS 10.12.4 and has had no problems. 
> Thus, it appears that Xcode 8.3 is the culprit. Anecdotal evidence suggests 
> that Xcode 8.3 has other problems, too, which may or may not be related to 
> the crashes.
