Ben, Currently on Darwin and apparently Solaris as well, we have build failures when gcc trunk is built without resorting to --disable-multilib on hardware that doesn't support 64-bits. See PR21561.
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 :) -eric
