PATCH 1/1 UML - Fix symlink loops

[ This should go into 2.6.24 - it's simple enough and people are complaining about this ]

symlinks to directories in the non-O= case were lacking -n, which meant that, when the link already existed, a new link pointing at itself was created in the target directory.
