These changes simplify the Makefile and handle these 5 ways to build
Landlock tests:
- make -C tools/testing/selftests/landlock
- make -C tools/testing/selftests TARGETS=landlock gen_tar
- make TARGETS=landlock kselftest-gen_tar
- make TARGETS=landlock O=build kselftest-gen_tar
- make -C /tmp/linux TARGETS=landlock O=/tmp/build kselftest-gen_tar

This also makes $(KHDR_INCLUDES) available to other test collections
when building in their directory.

Shuah, could you please merge this patch (and the USERCFLAGS/USERLDFLAGS 
one if that's OK) to -next? This is fixing an issue in the current 6.0-rc5 .

Anders, can you please check that this fixes your issue?

I took the liberty to pushed it in -next with my tree: 
https://git.kernel.org/mic/c/a52540522c9541bfa3e499d2edba7bc0ca73a4ca

Please let me know when you can take it in your tree to include it in 
the next -rc.

Regards,
  Mickaël

I plan to push it to Linus tomorrow, I'd like to get some feedback by 
then though.

Looks good to me. Thanks for doing this. Linux Plumbers travel and
subsequent being under the weather caused the delay in a response
to this patch.

I also saw your pull request to Linus.
