If A DEPENDS on B and you want A (you bitbake A), do you need the
package from B? The answer is you don't, you only need B to stage.

The dependency chains tell bitbake when it needs to build the package
and it only does thinsg which it needs.

This is totally configurable. You could add something to local.conf
which always caused dependent packages to build if you so wished...

Add some details about the options to the bitbake manual is on my todo
list and is one reason I've not made the imminent bitbake release.
