I'm not sure my "suggested-by" should be on this, since the idea of adding
an extra buildable option is not mine here. I actually think I prefer the
previous approach based on your original suggestion of always skipping
unbuildable examples. Two reasons for that:
* I'm not fully sure of the value of installing examples that can't be
  built, which was the original issue you raised.
* I don't like mixing together two separate things - examples to build, and
  examples to install in a single option.

Therefore, I think we should choose one of two less confusing paths -
either lets just always install all applications, or let's always install
only those apps which can be built. I'm not massively concerned either way
which is chosen, but I don't think we should try and support both and
overload options to do so.
