The idea is that some systems (primary or particularly secondary
systems) can have a default operation specified by :build-operation
that isn't load-op.

Thus you can declare make targets for creating executables, printing
documentation, etc.

Admittedly, you could do the same with fake secondary systems that
have an :in-order-to ((load-op (,build-operation ,real-target))). But
I figured it would be nicer to have a more direct solution.
