9. AOT -> Link -> Binary
MonoTouch uses Ahead-Of-Time compilation to produce
a single statically compiled ARM binary
AOT compilation pre-generates the native code that the
JIT would normally generate from IL
Links this together with the JIT-less runtime into a single
native binary that can be signed
