If you'd just like a link to that category index in the link-blog, then you might just want to use something like this:
CODE
<a href="http://your-site.com/linkblog/archives/cat_<$MTArchiveCategory dirify="1"$>.html"><$MTArchiveCategory$> Links</a>
That assumes the normal setup for the filenames, but would be the basic way to provide a link that you could customize for your own setup
