Subject: [PATCH v2 1/2] selftests/Make: Recursively build TARGETS list
>From [1]:
> Please look into a wayto invoke all of them instead of adding individual
> net/* to the main Makefile. This list seems to be growing. :)
I might have misunderstood what was suggested... Here is an attempt to
let sub-selftests define their own $(TARGETS) directories.
