Without doing it recursively, it's already tricky, since ...

[rocketmouse at archlinux Desktop]$ for l in $(find . -type l);do [[ "$(readlink $l)" = "$item_name" ]] && echo -e "\n### ### ###  NOT OK  ### ### ###\n";done

False positives could be caused by links that link against paths that
are only mounted on demand.
