Xcode 5.1.1 has a bug where using an SDK selector ([sdk=macosx*]) on the LHS of a variable definition and a sub-variable expression on the RHS causes the entire expression to be ignored.

In other words, when building with Xcode 5.1.1 on 10.8, this line in FeatureDefines.xcconfig is completely ignored:

ENABLE_WEB_REPLAY[sdk=macosx*] = $(ENABLE_WEB_REPLAY_macosx_$(CONFIGURATION));

The workaround is to switch back to using PLATFORM_NAME and remove the SDK selector as long as 10.8 is supported.
