Fix target dependencies and enable parallel again2.0.0-pre.2
We can now use 'make -j 32' again. All tests pass. There might
be some issues left with the areas that are not fully tested
yet (some plugins).
A few changes in behavior:
* 'make app' will also do 'make deps' unless SKIP_DEPS is set.
You can use 'make app-build' instead to just build the application.
* 'make rel' will also do 'make app' (and therefore deps). There
are no alternative target to keep the old behavior at this time.
