This is, technically, a regression from 6.2, so it's not

In gitlab #1097 the author comments that:
https://gitlab.com/qemu-project/qemu/-/issues/1097#note_1044810483
"there are several distributions still available on 32-bit powerpc, e.g.
Adélie Linux, for now still Void Linux, afaik Debian and OpenSUSE also
still build packages"
I checked these claims. Latest version OpenSuse LEAP doesn't support
ppc32 bits:
https://get.opensuse.org/leap/15.4/#download
The last Debian that supports ppc32 was Debian 8:
https://www.debian.org/ports/powerpc/#powerpc
"Debian on 32-bit PowerPC (powerpc)
It first became an official release architecture with Debian GNU/Linux 2.2
(potato) and had retained that status until the publication of Debian 9
(stretch).
The last supported release for 32-bit PowerPC is Debian 8 (jessie)"
And Void Linux doesn't seem to support any PowerPC flavor:
https://voidlinux.org/download/
Adélie Linux supports ppc32. I can also add that FreeBSD also supports ppc32.
Checking about/build-platforms.rst I can see that we would only somewhat
care for FreeBSD here, since Debian 8 is already out of our support
window.
All that said, I don't have strong feelings against re-enabling it, specially
because this build issue was deliberated caused by us.
However, after re-enabling it, I would only care about build bugs that are
reproduced on ppc32 FreeBSD.
