This is only the runtime (interpreter or JIT), not the class
libraries.  You still need to compile a different runtime for
different systems.  The class library would still be the same.

As I said, this is only in the runtime, not in the libraries, that is
why I proposed an external "annotation" system that would be resolved
by the runtime.
