You can request ATC permission to deviate from these requirements; " For operation of an aircraft that is not equipped with ADS-B Out, the request must be made at least 1 hour before the proposed operation" (91.225g2).

I doubt that this one hour requirement would be strictly enforced in a land out situation!

You can get any of these restrictions waived by declaring an emergency, but you will likely have to explain to an FAA examiner how you got yourself into the emergency in the first place. The examiner probably will not have dealt with gliders before, so you will have to explain all of the basics, including what thermals are and how unpredictable they are.
