At present, the only real way to do this is to add a t-* file for your
own purposes, or modify an existing one.
I would very much like to see GCC grow a way to specify the set of
multilibs at configure-time; until we do that, all we can do is create
more and more configurations, without covering all the cases people care
about. But, this is a significant effort because of lot of stuff is
baked into the build process.
