fix for busybox ls to show symlinks in all cases

[Eric Delaunay <delaunay@lix.polytechnique.fr>]

Apply the following patch to fix problem with ls not displaying symlinks.
readlink() need to be called with the full pathname otherwise is does not find
files outside the current directory.

Sorry I just have email access for the moment, so I cannot commit it myself to
CVS.  Could someone do it for me?

Regards.
