But that raises an interesting question. What happens if you try to load a library compiled with `-march=armv8-a+sve` on a non-SVE system? Is the ELF flagged to require SVE so it will fail to load? I'm hoping this is the case -- if so, everything will work as it should in this PR, but I honestly don't know. (After spending like 10 years working with building, I still discover things I need to learn...).
