It'd be possible for non-cross compiles to engineer something up
in the configure, but it would only work for occasions when you already
had a compiler installed that supported the 64-bit multilib since you'd
need to have it around to build it. Or, as Ben said, it's only when you
have already built the new compiler that you'll know and might as well
pass --disable-multilib and start the build again :)
