You are talking about some non-coreutils readlink utility.

The readlink from coreutils works this way:

$ readlink --version |fgrep readlink
readlink (GNU coreutils) 5.3.0
$ readlink -f /usr/share/../1/2/3
$ readlink -v -f /usr/share/../1/2/3
readlink: /usr/share/../1/2/3: No such file or directory
$ readlink -v -e /usr/share/../1/2/3
readlink: /usr/share/../1/2/3: No such file or directory
$ readlink -v -m /usr/share/../1/2/3
/usr/1/2/3
