The new SD_ELF_NOTE_DLOPEN_ANCHORED() macro utilizes the 'o' assembler flag (SHF_LINK_ORDER), which requires binutils >= 2.35 or LLVM >= 18. If an LLVM version older than 18 is encountered, the macro automatically falls back to the non-anchored variant. This non-anchored fallback relies on the 'R' (SHF_GNU_RETAIN) flag, which requires binutils >= 2.36 or LLVM >= 13. Since the codebase now unconditionally adopts SD_ELF_NOTE_DLOPEN_ANCHORED() tree-wide, the effective minimum toolchain requirements become: - binutils >= 2.35 (to support the 'o' flag) - LLVM/Clang >= 13 (to support the 'R' flag fallback for versions < 18) Update the minimal toolchain versions in the README to reflect these requirements for building systemd.
