Makefile fragment that generates makefile targets to call make with a given target on all apps/* subdirs.
Useful for erlang projects using erlang.mk that have apps/{app1,app2,app3..} structure (which rebar doesn't mind). Eg: call "make app" and it will call "make -C apps/app1 app; make -C apps/app2 app; ..." for you.

Hello Richard,
thanks for a snippet - this is very nice.
How do you build an app release with this make file? In the situation when you have an apps dir you would need to build a release using relx.config which would live in the root dir (which contains apps) and the release should pack all the applications in the apps?

This is in my top-level Makefile, with the "real" makefiles that include erlang.mk in my various apps/ dirs.
