Lovely, thanks! I've pushed your patch now.

The configure parts for metalink might still need to check if a "suitable"
crypto lib has been specified or detected already and either error out if not,
or just disable metalink support again.

Alternatively, libmetalink should be made to use/provide its own set of crypto
functions to allow curl builds without SSL/SSH support.
