No. Feel free to submit changes upstream; it's a good idea. I think you'd have to get multilib builds working properly for libstdc++ on x86. The multilibbing scheme in gcc is somewhat confusing to me (despite doing some work on it), but if you can grok it, go for it. It's probably better understood by porters for arches where multilibbing is already used by default.
