For Habsburg Level 1 (Migratory Herders), does it check all Build Cards, or just those in the normal Build Space?

The intent is that it only checks cards in the Build Space printed on the Invader Board, but that isn't explicitly spelled out for space reasons (and because it doesn't matter 99% of the time). If you play it as written (also checking Build Cards in other places), that's totally fine.
Situations where it makes a difference include are playing double-Adversary with England Lvl 3+ (the High Immigration step has Build Cards) and the Event Card "Farmers Seek the Dahan for Aid" (which can turn a Ravage Card into a Build Card).
