[issue81] possible readline license violation

[Matt Emmerton <bugs@xxxxxxxxxxxxxxxxxxxxxxx>]

Matt Emmerton <matt@gsicomp.on.ca> added the comment:

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.
