It does seem a little silly, but there are cases where it is useful.  If
you don't need that feature, then don't use it.

To me, the most obvious use is in recursive make, when you want a
top-level make to have it set, but not a sub-make.  If Makefile
contains:
> all: sub-folder
> sub-folder:
>       $(MAKE) -C $@ all -l
Then even if we use "-l 2.5" when we call make, the sub make won't have
a load limit.
