This addresses the scenario "mobile build host" where the resolv.conf as
once generated during bootstrap and then propagated into the
buildchroots as well the image rootfs may have become stale.

You probably want to use "cp -L", modern network managing tools often
work with symlinks and there seem to be versions of cp that do not
default to "-L". Not sure whether we can get problems in Isar, but
the gentoo manuals always mention "-L" for that step.
