While I understand the desire to shrink gerrit buildbot build times, I 
wonder whether it is a good idea to do so by making those builds less 
deterministic and precise.  The building of external libraries is for 
example influenced by solenv/gbuild/.  Given that at least one use-case 
for gerrit buildbots is to let a developer verify the impact of his 
changes on platforms he does not have easy access to, it might be 
counter-productive if those builds silently do not build what the 
developer would expect them to do.
