Bug#588776: base-installer: please don't rely on /proc/mounts, which is not available on Hurd

[Jeremie Koenig <jk@jk.fr.eu.org>]

Package: base-installer
Version: 1.108
Tags: patch
Usertags: gsoc2010

Hello,

bootstrap-base starts by checking that something is mounted on /target,
using /proc/mounts. On Hurd, /proc/mounts does not exist, and
bootstrap-base fails as a result.

The attached patch short-circuits the /target check when /proc/mounts
does not exist.
