It's automatically updated by building the documentation from current
head-of-git, so the answer is "submit a patch to change
docs/about/build-platforms.rst". (That's a pretty new file, and
the stuff about CPU architectures has gone in only very recently,
so it's not unsurprising if Marc-André and I got some things wrong:
we were just looking through tcg/ to see what it seemed to have
support for.)

The structure of the build-platforms page currently assumes that
"supported host CPU architectures" and "supported host OSes" are
basically orthogonal, because historically the nature of QEMU has
been that this is more-or-less true. If we want to try to be more
specific about that then we'd need to re-jig things.
