Thank you David for looking it this!

In Main.gmk, we keep the dependencies separate, inside a big 
conditional, to support the "-only" targets. Basically we need to be 
able to disable dependencies.

Hm, thinking some more on this, that change is not needed right now. I 
had been playing around with (and plan to propose in a followup), 
splitting up the bundles target so that the different bundles can be 
created in parallel. In that case, each bundle will need specific 
prerequisites for optimal parallel potential.

As it is now, if the default make target (as defined with the 
--with-default-make-target configure flag, which the Jib profile 
defines) does not depend on product-images and test-image, the bundles 
target will fail. In reality this shouldn't happen unless someone does 
something really weird or misconfigures Jib.
