Agreed we shouldn't auto update the buildroot.

Crazy thought:

Lazy chain.  I personally am one of the people that needs to do multiple 
builds at a time with the Firefox set of updates.  I do not like the 
idea of being forced to specify all the builds at one time, one bit. 
There are many cases where I wait to see the results of a build before 
pushing another build because it might alter what goes into that build. 
  The ability to do make build ADD_TO_BR=firefox-x.y-z or similar as 
something I need to add to dependent packages is much more appealing 
than having to specify everything at once.
