[PATCH] kbuild: Disable depmod in cross-compile kernel build

[Deepak Saxena <dsaxena@plexity.net>]

When building embedded systems in a cross-compile environment and
populating a target's file system image, we don't want to run the 
depmod on the host as we may be building for a completely different
architecture. Since there's no such thing as a cross-depmod, we
just disable running depmod in the cross-compile case and we just
run depmod on the target at bootup.
