[PATCH v2 1/3] busybox: Exclude .debug from depmod

[Saul Wold <saul.wold@windriver.com>]

As with the kmod version of depmod, exclude .debug from being
searched. Since busybox does not use the depmod.d and any 
configuration file option is ignored we just hardcode it.

+Subject: [PATCH] depmod: Ignore .debug directories
+
+The .debug/<module>.ko files do not have the correct symbol information
+since it's split away from the actual <module>.ko file. Just ignore it.
