Good point. Did it require tabs for *every* indentation ? Or only for make 
recipes ?

There are a lot of line continuations in variable definitions, which I suppose 
could simply be with spaces.

But in any case, if tabs are required for recipes, I'd consider that a good 
motivation to consistently use tabs where-ever possible.

So unless someone disagrees, it will be tabs.
