This adds a new configuration directive to depmod that causes depmod to exclude a give path entry like .debug. kernel-dbg provides the modules .debug/<module>.ko files and when installed either directly or when dbg-pkgs are selected this can cause depmod to fail. This patch will be submitted to upstream kmod.
