Updates when using Xcode 5.0.1 on MacOS X 10.9, and also for arm64 iOS targets.
It looks like all the *_stret functions do not exist in the arm64 runtime, so we can't even reference them in code and must #ifdef them out.
Also on arm64, BOOL seems to be encoded as "bool" (the 'B' objcType, or _C_BOOL) rather than the historical 'c', but NSValue can still use 'c', so we need to have those compare as equal.
There are warnings now when undeclared methods are used in @selector statements, so add some @interface sections to quiet the warnings.
In one place, a method lookup wasn't working (@dynamic property) but we still got a method signature, so changed to use the passed-in SEL.
Add OCMockLibTests target for running unit tests on an iOS device or simulator.
