Auto-generated Make-sis build step fails with non-app/non-deployment projects

QtCreator is so kind and automatically creates a Make-sis build step for each Symbian build configuration.
That is good for .pro files that generate an executable (Template=app). It fails for other profiles.

Creator is currently getting stuck in Evaluate/Evaluate/Indexing heaven (Yes, twice Evaluate). So, I cannot provide the exact error message. But it says something like: "make sis does only work for app template profiles or profiles that have a DEPLOYMENT statement."
