First, it seems someone changed something in the master in the last few days
that broke linking when building on linux PPC.
I pulled the master a few days ago, and it still builds and links fine, but
something has broken it now, please fix.

Unless someone else is aware, you might need to bisect this. Perhaps
post the above output along with compiler and version to qemu-devel as
it could easily have been introduced via a non-PPC patch?
Also, it seems with KVM I can't use -cpu host with qemu-system-ppc or
qemu-system-ppc64, I've read a few people on the web where able to use this,
but it doesn't work for me on a Powerbook G4 with Debian 8.10 host, with kernel
qemu-system-ppc64: unable to find CPU model 'host'
qemu-system-ppc: unable to find CPU model 'host'
Not sure if something changed from older verssions, or I need to add something
to ./configure to get -cpu host to work?
Perhaps one of the PPC guys can confirm how/why this has changed?
Also, using -cpu G4 or -cpu 7410, -cpu G3, -cpu 604, with --enable-kvm results
in this when booting the Mac OS 9.2.2 Retail CD:

With --enable-kvm qemu-system-ppc can boot Mac OS X Panther v10.3.0 CD, but installing fails. With Mac OS X Triger 10.4.x it boots and installs, but the install seems to get corrupted. Seems an issue with disk corruption with kvm enabled?
Even when I just use emulation of the G4, without kvm, system won't boot to the

former. Regarding the G4 CPU I'm not sure whether that's a compatible
setup for the given MacOS version and ROM, but someone else would need
Seems there is some bad reversion going on in the latest builds from the master
as far as Linux PPC 32bit hosts.
I remember when Alex did the initial MacOS X work back around 2015 he
seemed confident that things were working well then, so it might be that
you need to go back a few years to see where things started to go amiss.
Regarding OS 9 IIRC the issue there was related to KVM not supporting
the correct MMU modes (which is likely given that the new MMU index code
tended to break OS 9 as it was being developed) so that might require
some kernel work.
Given that very few people have access to your hardware there's a fair
chance that you'll need to do quite a bit of the investigation work
yourself, but there are people around who can point you in the right
