Would this suite your purpose ?
target: my_dir/Makefile
$(MAKE) -C my_dir
I'd amend that a little, like so:
target:
-$(MAKE) -C my_dir
Here's what I changed:
* I didn't make `target' depend on a file named Makefile, since I'm
not certain that such a file actually exists (perhaps you named it
`foo.mk').
* I put a dash in front of the command, so that if it fails (because
the directory doesn't exist, for example) your top-level make will
*not* fail -- I suspect this is what you want.

If you can't change your underwear, can you be sure you have any?
