Tested the proposed patch from Sergei Trofimovich, and it solves the problem, while doesn't break the other archs I use (mips64,arm,aarch64 also tested).

This impacts whole python3 based Gentoo ebuild system (package management), and renders linux user mode alpha emulation in chroot environment building useless, more or less.
