Mike,

see bug 13986 and the comments there as well:
http://sourceware.org/bugzilla/show_bug.cgi?id=13986

abilist does not work at all right now with ports.

Btw. in the discussion regarding "what is glibc-ports", one proposal was 
merging ports back - and if that's the road we take, we could also add 
ia64 back in the normal space...
