From: Mathieu Desnoyers <mathieu.desnoyers@xxxxxxxxxxxx> commit 4f11410bf6da87defe8fd59b0413f0d9f71744da 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=...).
