From: Mathieu Desnoyers <mathieu.desnoyers@xxxxxxxxxxxx> commit 0d2cace5af50806a6b32ab73d367b80e46acda0f 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=...).
