So it's time to deprecate them and the corresponding 32-bit host environments now. This is a follow-up patch series from the previous discussion here: https://lore.kernel.org/qemu-devel/20230130114428.1297295-1-thuth@redhat.com/ where people still mentioned that there is still interest in certain support for 32-bit host hardware. But as far as I could see, there is no real need for 32-bit host support for system emulation on x86 and arm anymore, so it should be fine if we drop these host environments now (these are also the two architectures that contribute the most to the long test times in our CI, so we would benefit a lot by dropping those).
