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.
