binutils-2.39 enabed a few warning by default (https://sourceware.org/pipermail/binutils/2022-August/122246.html): > The ELF linker will now generate a warning message if the stack is made executable. Let's suppress the warnings in assembly files by adding non-executables stack markings. This fixes at least systemd build which uses '-Wl,--fatal-warnings': https://github.com/systemd/systemd/issues/24226
