From: Mathieu Desnoyers <mathieu.desnoyers@xxxxxxxxxxxx> commit e81ff69f66969a16a98a2e0977c1860f1c182c74 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=...).
