Daniel Dunbar e9da222f2f build/SDKs: Sketch a minimal stub SDK for Darwin. 
- Motivation is explained in the README, but basically it is convenient to be
   able to build compiler-rt free standing. Since our external dependencies are
   so small, we can achieve this relatively easily by just stubbing out the
   declarations of the external dependencies.
 - This is in no way, shape, or form intended to be complete, it is just the
   minimal stubs necessary to support the stuff we use.

README.txt 

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.
