So once again you caused big breakage of x86:

https://qa-reports.gentoo.org/output/gentoo-ci/eadddb4/output.html#app-emulation/domi
https://qa-reports.gentoo.org/output/gentoo-ci/eadddb4/output.html#app-emulation/qemu
https://qa-reports.gentoo.org/output/gentoo-ci/eadddb4/output.html#media-sound/pulseaudio
https://qa-reports.gentoo.org/output/gentoo-ci/eadddb4/output.html#sys-boot/grub

Since you already caused similar breakage lately, you should've really
tested it this time.

Please fix it and subscribe gentoo-automated-testing, and fix your
mistakes as soon as they appear.
