lib b : b.cpp : <dependency>stage-a ;

Where's the catch, you'd ask. The catch is that the <dependency> is not 
implemented.

I really can't promise to implement it for this milestone, since I'd like to 
make the final round of optimization. However, if you're willing to invest 
half-an-hour, you can implement this yourself. The recommented course
of actions is:

1. Define new feature <dependency>. Be sure to specify 'dependency' attribute 
for it.
2. Go to virtual-target.jam, and action.actualize-sources method.
3. Grab all <dependency> properties from self.properties via call to 'get' 
method on self.properties.
4. Add the result to 'self.dependency-only-sources'
