I don't think it is actually the consensus, only Arch Linux has chosen this solution, and building the whole glibc with this option will have an impact of the performances for all binaries, not only the broken Steam ones. I therefore don't think it's the right way to fix the bug.
For Fedora, I disabled multiarch support for the i386 builds because it's not entirely unlikely that there will be similar issues.
If we could assume SSE2 support and built the distribution with -march=x86-64, we would likely have to go the -mstackrealign route. But this is just an educated guess.
