From: Gert Wollny <gert.wollny at collabora.com>
os.path.exists doesn't return True for stale symlinks, but they are in
the way later, when a link/file with the same name is to be created.
For instance it is conceivable that the pointed to file is replaced by
a file with a new name, and then the symlink is dead.
To handle this check specifically for all existing symlinks to be
removed. (This bugged me for some time with a link libXvMCr600.so
always being in the way of installing this file)

It could also be that the problem is elsewhere, but at least here it
manifests itself and this patch fixes it.
