Dear Mr. Marek, dear all,

I have detected a hidden failure while building the kernel. If
--with-rootprefix is set for kmod, then depmod will look for modules
installed at the location $ROOTPREFIX/lib/modules/<version>. The
kernel build system does not know anything about $ROOTPREFIX, and so
the wrong directory is created for the test if the hack is needed for
an older versin of depmod at scripts/depmod.sh:19 mkdir -p
"$tmp_dir/lib/modules/$KERNELRELEASE". That is why "$DEPMOD" -b
"$tmp_dir" $KERNELRELEASE will always fail

I think we can revert the hack, because the three-digit version number
will stay for foreseeable future and depmod is not the only tool that
used to rely on this. However, what you describe looks like a bug in
kmod's depmod. -b sets the basedir, depmod should not prepend it with
any compiled-in string.
