Subject: [PATCH] selftests: x86: Fix incorrect kernel headers search path
References: bsc#1012628
Patch-mainline: 6.2.3
Git-commit: ac5ec90e94fe8eddb4499e51398640fa6a89d657

commit ac5ec90e94fe8eddb4499e51398640fa6a89d657 upstream.

Use $(KHDR_INCLUDES) as lookup path for kernel headers. This prevents
building against kernel headers from the build environment in scenarios
where kernel headers are installed into a specific output directory
(O=...).
