When using newer builds of clang with xcodebuild, the following output is spewed to STDERR for every single clang invocation:

2014-04-01 09:56:33.518 xcodebuild[32115:db03]  DVTAssertions: Warning in /SourceCache/IDEXcode3ProjectSupport/IDEXcode3ProjectSupport-6080.2/Xcode3Core/LegacyProjects/Frameworks/DevToolsCore/DevToolsCore/BuildSystem/BuildCommandResultsPostprocessing/XCClangResultsPostprocessor.m:88

Please file a bug at http://bugreport.apple.com with this warning message and any useful information you can provide.

The filter-build-webkit script should know how to ignore this useless output when combining STDOUT and STDERR for the build command.
