VFIO PCI never worked on PPC32 nor ARM, S390x is 64-bit, it might have

Are these defined for the host or target?
host.
No, Zoltan is correct. They are defined for the target, so if you build for 32-bit ARM
you'd still get things with "depends on AARCH64" in qemu-system-aarch64. You
can check that you have
AFAICS, you can't build qemu-system-aarch64 on 32-bit ARM anymore. Can you ?
Thanks,

As per commit 6d701c9bac1d3571e9ad511e01b27df7237f0b13 "meson: Deprecate
32-bit host support", support will be fully removed in 2 releases and
it doesn't need to be addressed by VFIO.
Note that a deprecation *allows* full removal in 2 releases. We have a lot of
things that are deprecated but have not been removed. For example
Short-form boolean options (since 6.0)
''''''''''''''''''''''''''''''''''''''
Boolean options such as ``share=on``/``share=off`` could be written
in short form as ``share`` and ``noshare``. This is now deprecated
and will cause a warning.
is deprecated to *allow* switching command-line options from the "qemu-options" parser to
the "keyval" parser that doesn't support short-form boolean options, but it's unlikely
that qemu-options will drop support for short-form boolean options.
