There is the wgNoFollowLinks setting to add rel="nofollow" to all external links, but no option to do the same for interwiki links. I have a patch to implement this which will shortly be forthcoming.

Untrusted sites should not be in the interwiki table, probably, hmm?
It makes no sense to do this.
Created attachment 3561 [details] new version of patch with option to apply nofollow only to nonlocal interwiki links This patch gives two config options: one which, if enabled, applies nofollow to all interwiki links; the other which, if enabled, applies nofollow only to nonlocal interwiki links (ie, to interwiki prefixes with iw_local set to 0).
I concur with Brion and Rob. This isn't particularly useful for core: more option clutter for no good reason.
