*/*.S: add non-executable GNU stack marking on ELF-linux
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':
