The good news: This seems to produce working binaries on my laptop and
my s390x systems.

The bad news: The build on the s390x system with Fedora 30 (yes, I
know) seems to be lacking various devices. The output of
'qemu-system-s390x -device ?' misses all of the
-transitional/-non-transitional varieties for virtio-pci devices, as
well as some of the vhost-user devices, and, rather bizarrely, the
gen15* and some of the z14 cpu models (this is on a z12, so it's not
that all 'newer' models are missing, and I don't think the system we
build on should influence the generation of models, even with an older
compiler). I checked the output from 'qemu-system-x86_64 -device ?',
and it is missing the -transitional/-non-transitional virtio-pci
devices as well (did not check if anything else is missing as well).
The builds on the F31 (x86) and F32 (s390x, with -Werror disabled)
systems are fine.

Any idea? If it is a case of old tools/libraries, I think we need to
make sure that older supported distros (Debian stable?) still work fine.
