We actually have a change cherry-picked from upstream for the https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=2f959dfe849e0646e27403f2e4091536496ac0f0 glibc change - https://gcc.gnu.org/ml/gcc-patches/2019-10/msg01554.html , but only for arm, while it apparently broke either all or many other architectures (at least x86_64 and riscv64 are now reported).
