AFAICT GNU as never gets an option named `-generate-unused-section-symbols=yes`.
It just has a quirk that interprets nearly all `-g*` options as `-g`, which
indicates generation of some compile units for ELF symbols with the help of
`.size` directives.
It's very different from generating unused section symbols.
