#22 Dependencies between lint and test

Most projects probably run linting before testing.

At the moment the order of execution cannot be specified properly:

• test may depend on lint
• but still specific tests (e.g. test-python) do not depend on lint-python

We could use one of the following approaches for solving this:

• A) add a configuration variable (RUN_LINT_BEFORE_TEST) in order to let all modules add a module-specific dependency (e.g. test-python: lint-python)
• B) add a test-prepare target, which depends on the linting (and maybe other details). All module-specific tests must depend on it - or we must ensure somehow (ordered dependencies?), that the test-prepare target is fulfilled first.

The (undesired) relationship between lint and test was removed in 5a39e297c7.
