Remove default blogroll before installing wordpress in many sites

I wanna use wordpress in 10 sites i have – i was using joomla- and well i also dont want to use MU. So i wanna customize wordpress before installing it several times. The translation i downloaded in spanish included several default links (some to the translator site, fair, but some to their commercial sites, kind of unfair way to get pagerank out of my sites as those links are per default in this spanish translation of wordpress) So i wanna remove them by default as i wont be using the blogroll feature and avoiding going many times in deleting them on wp-admin/link-manager.php

Where is the code for these default links when we download wordpress? i thought it was link.php or link-import.php but i dont see any of their links there.

Thanks for your help ; )
