We can of course keep disabling small data as we're doing today, it's just a bit inconvenient. It affects Zig and Rust, and maybe other languages that use LLD as well.

Perhaps a reasonable compromise could be disabling small data when we know the linker is LLD? (At least until such time as LLD grows support for small data.)
