[Buildroot] [PATCH 1/2] target: ensure target/ dir is writable

From: Nathan Lynch <ntl at pobox.com>
If the source target skeleton is read-only (eg. because Buildroot's
source dir is), modifications to the output target (such as creating
/etc/hostname and /etc/issue) fail.
(This can happen if the Buildroot source dir is NFS-mounted read-only
to be shared between different machines, for example).

[yann.morin.1998 at free.fr: we use rsync now, not cp; --chmod=Du+w
suggested by Arnout; clarify commit log]
