The 747 (Classic at least) can do an auto-land without de-crabbing at up to 23kts of crosswind.
Pretty rough arrival though ... (only done this in the sim)
The norm for the 747 is to de-crab as much as possible during the flare, as late as possible because you can't lower the upwind wing - It'll scrape a pod at around 8° or so bank angle.
