Are you talking about binaries compiled for bare-metal embedded? In such cases you usually simply do not have `std`. And how do you think dynamic linking would help here? If anything, it will make total size bigger since compiler will not be able to perform dead code elimination. When people talk about big Rust binaries they often forget to strip debug information. Doing it can easily shed half of the binary size. And there are other relatively well known ways of reducing binary size (such as strategically using dynamic dispatch instead of monomorphization, using abort for panics, compiling with opt-level=z/s, etc.).
