1 Those tests are taken from http://news.dieweltistgarnichtso.net/bin.git.
2 Test parallel_2 removed, because goredo has no --jobs.
3 Test always_rebuild_1 removed, because always-target is rebuilt once per run.
4 stat call is replaced with portable perl script invocation in ood_*.
5 ood_* pay attention that "all" is always OOD.
