This works by extracting somewhere then adding it to (the beginning of) your path.
Includes llvm, lldb, clang, ldid, tapi, libtapi, and cctools-port.
You need to provide a SDK - /usr/share/SDKs/iPhoneOS.sdk is the default SDK path
This build adds support for tapi v4 and makes it smaller by dynamically linking shared objects.
cctools-port updated to 973.0.1
