Subject: depmod failure for modules-install of a cross compiled kernel.

Hi all,

I ran into a small but inconvinient problem today when doing a
modules-install. The tempory solution is do disable depmod
when corss compiling. See the patch below.

Regards

I rather keep the present situation in the hope that either depmod is
fixed, or functionality implemented where it blelongs.

When cross compiling, specify 'DEPMOD=/bin/true' on the command line to
turn it into a no-op.
