We can try that but it doesn't solve any of our problems (and we'd 
have to keep carrying the two-level dir patches).

(I've already decided some time ago that supporting real multilib 
stages is too much effort for insufficient gain and stopped publishing 
them. Until recently I still built them; since glibc-2.33 they broke 
and while I know how to fix things I haven't had time to do it yet.)

So if we keep the multilib scheme around, then IMHO only as internal 
workaround until we/upstream/... have figured out a better directory 
scheme.
