Thank you for the patch!

(It might be useful to add a "Fixes" tag as well to clearly indicate the
dependence with a specific commit and better understand the fix.)

(and add all the individual maintainers of the files you modify -- feel
free to use 'b4' to help you for this task ;-) )

I only looked at the modification here with MPTCP selftests and it looks
good to me. It makes sense because if KHDR_INCLUDES is not set, it will
be set later by lib.mk I suppose.

Just one small thing: I guess you can also remove "top_srcdir" variable
that is no longer used, right? I see that "lib.mk" uses a variable with
the same name but it overrides its value anyway. But it is likely I
missed something there :)

If indeed it is no longer needed, I guess a few Makefile can be adapted
according to:

  git grep top_srcdir -- tools/testing/selftests/*/

I guess most of these Makefile are very similar, no? For MPTCP, we
simply looked at what was done elsewhere :)

Cheers,
Matt
