Subject: [PATCH] toolchain.eclass: disable automagic CET for x86

It's not supported on 32-bit kernels anyway.

This got lost in b6bf005b843e3d6ee10aa1f088d93c4f89055cc6 when wiring
up arm64.

Bug: https://bugs.gentoo.org/916381
Closes: https://bugs.gentoo.org/939874
Fixes: b6bf005b843e3d6ee10aa1f088d93c4f89055cc6
