Hmm.. You need to tell sparse _some_ way which one you use, since sparse won't do it. Picking one at random is fine, of course. It doesn't even have to match the one you'll compile with, although that means that sparse will obviously be testing a different configuration than the one you'd actually compile. So I think having -D__BIG_ENDIAN__ in the sparse flags is better than not having anything at all (since otherwise it won't be able to check anything). And having something that matches the compiler would be better still.
