Comment # 2 on bug 1073357 from Andreas Stieger

Unfortunately Chromium no longer builds on 32 bit. The same goes for Mozilla
Firefox, where this remains an issue with rust dependencies.

For both packages this was announced ahead of time and found the agreement of
the development community. I am afraid this situation will remain so. The
number of requests for this in in no relation to the required engineering
efforts, also considering the situation with people willing to maintain the
i586 arch including ALL dependencies.
