The approach with UserBuildConfig does not work. I think it is because 
the UserBuildConfig is included before some other necessary stuff 
happens with the targets (they need to be added to the "container" 
first AFAIR). Ingo would know the details I guess.

As for adding them in the default HaikuImage. The only thing I could 
see is that it causes the USB stack to be loaded earlier. This 
shouldn't really matter though. It might delay the boot process if the 
stack isn't kept loaded, but that would be a bug that has to be fixed 
then anyway. Through the presence of usb_disk we currently load the USB 
stack during boot anyway. So if we want the images to be USB bootable 
by default we can certainly just add these targets.
