Looks like most of the versions mentioned in https://gcc.gnu.org/install/specific.html need to be updated to at least the version that was mentioned in libstdc++'s manual. hppa*-hp-hpux11, i?86-*-linux*, and sparc-sun-solaris2* all mention versions older than 2.15.9. At least https://gcc.gnu.org/install/prerequisites.html recommends 2.35+ (due to LTO requirements).
