interworking and multilib

[Sean Kelley]

I have been trying to get a functional interworking toolchain going.
My settings follow this post.  The problem I have come to determine is
that even though I specify intworking for GCC configuration, it comes
in to trouble because multilib is not enabled:

How does one go about enabling it through crosstool?

Thanks,
