Euhm, while workable I don't like that approach.  And I conclude that
the way the OPTIONS system currently works has a serious shortcoming, in
that it does not report changed defaults to the user.

Basically in this situation ("default changed") we'd need to:

1. present the options form again
2. mention to the user that the default has changed
3. let him choose.

What might help in the longer term is having sort of tree/four-state
options, with "user-set to off" "user-set to on", "user does not care"
and/or "user said go with whatever the default is".

Arguably we might have wanted to kill the OPTIONS on cups* altogether,
and waive the BROKEN tag this time

Dirk, do we have any hints that the CUPS-refuses-GNUTLS will be resolved
in the foreseeable future?  If not, can we just bite the bullet and
remove the OPTIONS and force OpenSSL builds even though it might cause
license concerns deeper down the dependency tree?
