"make kselftest" fails with "Circular Makefile.o <- prepare dependency dropped." error, when lib.mk invokes "make headers_install". Make level 0: Main make calls selftests run_tests target ... Make level n: selftests lib.mk invokes main make's headers_install The secondary level make inherits builtin-rules which will use the rule to generate Makefile.o and runs into "Circular Makefile.o <- prepare dependency dropped." error, and kselftest compile fails. Invoke headers_install target with --no-builtin-rules to avoid circular error. In addition, lib.mk installs headers in the default HDR_PATH, even when build relocation is requested with O= or export KBUILD_OUTPUT. Fix the problem by passing in INSTALL_HDR_PATH. The headers are installed under the specified output "dir/usr". Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
