I wrote something like this. It is able to track owner of each files of 
target/ and host/. It generates list of owners[1][2]. These list may be 
usefull to generate binary packages. 

I am also able to generate list of overwritten files[3][4]. 

Once I have list of owners in host/, I can track which files are 
accessed during build and compute dependencies between packages[5]. 

As you notice, it is only a proof of concept. There is plenty of false 
positives and I noticed many problems. Especially, current script is not 
very reliable when I launch compilation from a dirty directory. 

It is currently done by launching a daemon which watch target and host 
(using inotify) during each step a built. This daemon log access to 
files and another script post-process it. (I think, I would have far 
better results if I maintain in real time a database of owners of all 
installed files). I may send patches if you are interested (but they are 
a little ugly).
