That will solve the ILP32 side of things and I am ok with doing that
but not it does not solve that right now AARCH32 and AARCH64 are
incompatible.
You could say AARCH64 LP64 is currently broken because of this
incompatible but nobody has complained until now.

So the question becomes do we care enough about the incompatibles
between AARCH32 and AARCH64 to fix this and go just worry about ILP32
and LP64?

Thanks,
Andrew
