quilt/hackweek-11-16-setup-fix-create_symlink-corner-case.patch

From: Jean Delvare <jdelvare@suse.de>
Subject: setup: Fix a corner case in create_symlink
Upstream: Submitted (2015-02-03)
References: boo#916007

When a link's target is the directory it lives in, create_symlink
would erroneously link to "..". Fix the code to properly link to "."
instead.

Credits to Robert Milasan for spotting the bug.
