Directly invoking make coverage-report as a target results in an error because
its prerequisites are missing,

This patch adds the compile-test prerequisite, which is run only once each time
the compile-report target is invoked. In practice, the developer may decide to
review the coverage-report results without necessarily rerunning for this
coverage-test, if it has already been run.

This is the fourth revision of the patch. Compared to the third:

- @make -> $ (MAKE)
- drop touch coverage-test.made from the coverage-test.made target

The result happens to be identical to what I already have in my tree.

Thanks for taking care of the details of dependencies.
