[Mandy Chung]

This looks fine and good to see the hardcoded exception replaced.

In make/Main.gmk, we dynamically create targets for building the java and native parts of modules and the dependencies between them. This code assumed that all modules with native parts also had a java part, with one explicit exception. With this fix, the dependencies are only created for modules that actually have both a native and a java part.
