The problematic part is figuring out what ISA extensions are supported by the rust compiler being used (and by bindgen), and deciding what to put in -march as a result. I think it is unlikely to matter for you, unless you're aggressively mixing versions for different parts of your toolchain. I do intend revisting this, probably after the min. version for rust gets bumped, I've just been really busy with other work the last weeks.
