[evolution-patches] e-d-s configure fails to properly detect kerberos 5

[guenther <guenther rudersport de>]

Just a heads up, that there is corrected code (though not a patch) by
Joseph in bugzilla, to fix this issue.

  http://bugzilla.gnome.org/show_bug.cgi?id=312806

Please, if someone (e-d-s maintainers?) can have a look at this code and
get it in, this would be great. Thanks...
