The default for non-x86 is now the same as x86: pie is used if supported, and may be forced via --enable/--disable-pie. The original commit (40d6444e91c) said: "Non-x86 are not changed, as they require TCG changes" but I think that's wrong -- there's nothing about PIE that affects TCG one way or another. Tested on aarch64 (bionic) and ppc64le (centos 7) hosts.
