The ubuntu:20.04 container ships gcc-9-riscv64-linux-gnu with binutils that cannot parse newer RISC-V ISA extension strings (zaamo, zalrsc, zca, zcd, zmmul) emitted by the Rust stable compiler, causing linker error "unsupported ISA subset 'z'". Ubuntu 22.04 ships gcc-12-riscv64-linux-gnu with binutils >= 2.38 which supports these extensions. Only the RISC-V entry changes; other Linux targets keep ubuntu:20.04 for maximum glibc compatibility. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
