Not only would you need a different libc, you would have to have _all_
other libraries compiled with this same other ABI. I suspect you
would have to get support into the kernel as well for it.

If you really want to do this, it would probably be better to approach
AMD and Intel with the suggestion of defining such an ABI; this is not
something Ubuntu can reasonably do (and I'll therefore mark this bug
as «Won't Fix»).
