working patch, no incremental linker support

Here's a patch that gets things going; it works on several testcases I've
tried.  I haven't run the test suite yet due to native testing requirements
yet, but I have tested a wide range of branch distances and such and things
look pretty good.

I'm also fairly certain this breaks when doing incremental linking.  Stubs are
now variable-sized when using this scheme, and the incremental linking support
is not yet (ever?) ready to handle that.  Making all stubs 16 bytes when using
the incremental linking support is a possibility.
