If I see it correctly, you don't need native compilation for each  
architecture, because the resulting code should be platform- 
indemendent (Java-classes). Also you're not really building any  
dynamic library to load in R. If both are correct, you can for example  
use configure instead of src/Makevars to build your Java code since  
this a) guarantees that it is run only once b) doesn't trigger the  
SHLIB building so you do't need a fake .so.

Cheers,
Simon
