Investigation reveals that although the two KRB5 utilities (kadmin, ktutil) 
link with -lreadline, they don't actually use the readline facilities.

The following patch removes -lreadline, and is buildworld clean.
Did you actually check this with -DWANT_KERBEROS (which fails after the 
patch was committed).
