i can see why bumping ver # is undesirable, but i don't think it's that big of 
a deal.  the ldso is a bit of a magic beast, so i don't think applying the 
same SONAME versioning rules is terribly important.  especially since ARM has 
already moved from ld-linux.so.2 for OABI to ld-linux.so.3 for EABI.  you 
could even argue that enshrining hardfloat is actually an ABI version bump, so 
ld-linux.so.4 is appropriate.  and really, once you bump the SONAME, injecting 
substrings like "hf" are no different.

i'm not familiar with ppc's embedded variants, so i can't speak to these 
examples

i'm not sure why you think that.  if people actually want to do multilib with 
these, then there's nothing stopping people from doing that, once the ldso's 
are in a unique path.

what Debian chooses to do with multiarch is up to Debian ... i don't think it 
should have any bearing here.
