yes, it's legacy cruft that we haven't been able to migrate away from
yet.  we were able to drop it on other arches because their multilib
users were largely non-existent, but amd64 has always had an extensive
user base.  if we can figure out how to migrate them, we will at some
point.  see:
https://bugs.gentoo.org/506276

since sparc's multilib userbase does not exist, we have time to fix
that mistake.  so if that diff above works for you, i'll just push it.
