I am not sure I like the idea of combining these two stages. There is a 
couple of reasons, mainly as it is different from standard use case and it is 
different from javac style support. I just browsed through all my own 
personal native code packages and they all do compilation and "linking" in 
separate sweeps. 

Also doing it in one task is different from how javac works. For instance, 
javac just does compilation. Aggregation of all the .class files into 
different output archives (ie jar/zip/ear/war etc) is done via a separate 
task. Considering that executable, static and dynamic libraries are just 
archives of object code (anyone remember the pain of the ar tool? ;-]) I 
don't think we should break this pattern. It could also lead to task becoming 
quite large.

Also would it be possible to make the cache directory for dependency 
information configurable.
