Do a full x32 world build and ensure all targets build correctly, fix any issues that come up.
This looks more generic. I guess the strategy to kill this one would be to do a full x32 build and fill in a bug for every major issue that comes up. I'll start with a 3 days estimation for this, end go from there.
This is a master issue for x32 support, since some issues depends on upstream move to Future.
This is no longer an issue, all dependent bugs have been resolved and the current x32 with poky world builds fine. Closing.
