Revert part of the earlier changes to fix the kselftest build when
using a sub-directory from the top of the tree as this broke the
landlock test build as a side-effect when building with "make -C

Building with this patch doesn't work, it gives this output:
make[3]: Entering directory
'/home/anders/src/kernel/next/tools/testing/selftests/landlock'
make[3]: Leaving directory
'/home/anders/src/kernel/next/tools/testing/selftests/landlock'
make[3]: *** No rule to make target
'/home/anders/.cache/tuxmake/builds/78/build/kselftest/landlock/base_test',
needed by 'all'. Stop.
I'm building like this:
tuxmake --runtime podman --target-arch x86_64 --toolchain gcc-12
--kconfig defconfig kselftest
which translates into this make command:
make --silent --keep-going --jobs=32
O=/home/anders/.cache/tuxmake/builds/78/build
INSTALL_PATH=/home/anders/.cache/tuxmake/builds/78/build/kselftest_install
ARCH=x86_64 CROSS_COMPILE=x86_64-linux-gnu- kselftest-install
This works well for me.
Interesting
Which commit is checkout?
I used the latest next tag, I tried to on todays tag as well
next-20220822 and I see
the same issue.
building without 'O=...' I can build the landlock tests...
Does this work if you revert this patch, commit a917dd94b832
building without this patch works, see below:

("selftests/landlock: drop deprecated headers dependency") and commit
f2745dc0ba3d ("selftests: stop using KSFT_KHDR_INSTALL")?
This patch mainly revert commit a917dd94b832, so I don't see the issue.
Cheers,
Anders
