its yasm which has the arch specific call. I don't really know how to do it in bitness specific way.
I have the same error.
same problem here on a portage-multilib system for a while now with app-arch/p7zip-9.20.1-r4. I think this should also be added to the tracker bug here: https://bugs.gentoo.org/show_bug.cgi?id=306835
