Arch Linux

When I try to build the firefox 92.0-1 package with an unodified PKGBUILD in a clean chroot (using extra-x86_64-build from the devtools package and an unmodified /usr/share/devtools/makepkg-x86_64.conf from the same package), I keep getting the following error:

I've attached logfiles of the entire package compile run, produced by running

extra-x86_64-build -c -r /mnt/archbuild > >(ts '%F_%H:%M:%S' | tee -a stdout.log) 2> >(ts '%F_%H:%M:%S' | tee -a stderr.log >&2)

I've had the exact same issue when trying to build Thunderbird 91.x for a few weeks now, even though building thunderbird 91.0.2 on 2021-08-23T13:05:06 CEST worked without issues. I've suspected LTO, but neither adding "!lto" not "lto" nor omitting it from the options array in the PKGBUILD resolved the issue.
