i don't see this as a problem

my point was: it works today and has no clashes.  that satisfies the "omg we 
have to ship something $now" and satisfies the requirement that only the Debian 
people are putting forth (and has already been violated by many targets): the 
ldso must be unique across all arches/multilibs.

i don't buy that it'll happen that soon (since ldso's don't get generated 
quickly), but that is certainly plenty of time for the Debian project to 
attempt to convince everyone else that multiarch isn't a waste of time.  and 
does so without holding up moving forward with a unified arm hardfloat abi.
