  The menu entries make less sense now. Either keep a comment above, or change 
all the prompts into "install isolinux" ...

  It is now possible that no image is selected at all. I think this will be 
pretty bad for the build - probably, everything will be built but nothing 
installed. So we either have to force one of the images to be selected, or add a 
check in the .mk file that at least one of them is selected. I'm not sure what 
the best solution is here.
