I'm trying to understand if my use of the $(file..) function is correct or
not. Based on tests/scripts/function/file, I cooked up this little file.mak:

rm file.out
$(file file.out, Hello)
$(file file.out, world)
@echo 'abspath

I'm not sure I'd go that far. $(shell ...) really _is_ useless in a
recipe because make will invoke a shell to run the recipe anyway, so why
have it invoke two shells? It's just redundant.
However, $(file ...) can be useful
