I did think about that, yes. However, I didn't figure out a satisfactory
way to solve it. The problem is that WriteFile, on GNU Make < 4, results
in a $(shell) call, which seemed worse than a chained call to echo, when
we already is in a shell command line in a recipe. I wasn't too keen on
creating a WriteFileInRecipe version either. So I couldn't figure out a
way to do that that I was happy with. But I'm open to suggestions (or
even better, working code :-)).
