And I've just sent a patch to completely remove that include directive
altogether: tools would register twice, wihch is not nice (built twice,
installed twice...)

I did not catch this during my tests, because that problem was hidden:
  - the $(wildcard) would return nothing,
  - $(sort) would happily have nothing to sort and would return nothing,
  - include would be happy to have nothing to include,
  - but each individual .mk files would already be included from top-level
    Makefile, in the correct order,
  - so I did not see the path was wrong and did not see the tools were
    registered twice.

Sorry for the mess... :-/
