We test these features:
- Multiple commands for the same (double-colon) target
- Different prerequisites for targets: only out-of-date
ones are rebuilt.
- Double-colon targets that aren't the goal target.
Then we do the same thing for parallel builds: double-colon
targets should always be built serially.";
