BTW this has now been done in git-HEAD, and should make ppc64 behave a bit 
more sensibly: It's possible to set a preferred arch for a given base 
architecture, so instead of 90% of packages getting renamed to .32bit, on 
ppc64 (and sparc64) the few 64bit packages are renamed to .64bit while 
leaving the rest alone.

Nothing has been done about the segfault as such, as I still have no idea 
where it's coming from but IF it's somehow related to the ridiculous 
amount of .32bit "compat" package renames.. it just might help anyway.

If you want to try it out in a safe manner (without overwriting installed 
version binaries etc), you can do this:
$ git clone
$ cd apt
$ ./configure --prefix=/usr --libdir=/usr/lib64 && make
$ su
# cp etc/multilib.conf /etc/apt/apt.conf.d/
# cd cmdline
# ./apt-get < stuff>
