I need to do the following:

--- gcc-4.0.2/gcc/config/arm/t-arm-elf  2006-03-07 15:37:44.922144680 -0500
+++ gcc-4.0.2.patch/gcc/config/arm/t-arm-elf    2006-03-07

will --with-multilib-list=arm-??? do that?

I found how the the tmake files are used in gcc-4.0.2/gcc/config.gcc. 
I added t-arm-elf to the case which handled arm-elf-linux.  If it
bombs out, I can try --with-multilib-list, although I'm not sure what
list I would pass in.
