+It is often convenient to be able to build compiler-rt libraries for a certain
+platform without having a full SDK or development environment installed.
+
+This makes it easy for users to build a compiler which can target a number of
+different platforms, without having to actively maintain full development
+environments for those platforms.
+
+Since compiler-rt's libraries typically have minimal interaction with the
+system, we achieve this by stubbing out the SDKs of certain platforms.

+The Darwin platforms are all similar enough we roll them into one SDK, and use
+preprocessor tricks to get the right definitions for the few things which
+diverge between OS X and iOS.
