If u-boot doesn't need any support libs, the existing compiler can
likely cope with that. If you need libgcc, then you will need multilib.

I'd like to get to a point where we can support this using multilib
however it might not all work correctly today. It would be interesting
to try it! The intent is to get to the point where it would work but
its not currently a priority as not many people have been asking for
it.

Cheers,
