If the kernel headers aren't installed we can't build all the tests. Add a new make target rule 'khdr' in the file lib.mk to generate the kernel headers and that gets include for every test-dir Makefile that includes lib.mk If the testdir in turn have its own sub-dirs the top_srcdir needs to be set to the linux-rootdir to be able to generate the kernel headers.

What is the reason for this SUBARCH block move to to scripts/subarch.include? Is this necessary for adding headers install dependency to lib.mk?
This is needed to create headers for cross build.
I am sorry for the delay on this patch. I am going to get this into 4.19. If anybody has objections, please let me.
Anders! Will be able to rebase the patch and send me the latest. I think I have Acks from kvm, android, and vm so far.
I may be missing something about the tools/ directory, but why isn't it like this?
kselftest: headers_install $(Q)$(MAKE) -C $(srctree)/tools/testing/selftests run_tests
That wont work if you cross compile, since you wont run the tests where you build them. Then you can argue that we should break it up in a build and run rule. However, my understanding how people just build and run the the tests for that particular subsystem that they develop for, like: make -C tools/testing/selftests/<subsystem>/
