Subject[PATCH 29/34] selftests: x86: Fix incorrect kernel headers search path
Date
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=...).
