A little off topic, but a fringe benefit of using the -p flag to
mkdir is that it never complains about directories which already
exist. This is even guaranteed by POSIX, which says "Each dir operand
that names an existing directory shall be ignored without error" when
-p is used. I often use -p to avoid the loop-and-test above, even
when making single-level dirs. So the above could just be
__dummy := $(shell mkdir -p $(MKDIRS))
saving both processes and keystrokes.
