Don't get me wrong (I mean I'm rewriting in Rust), but: LTO and static compilation are available to binaries built and statically linked with musl (it's one of the main advantages musl has over glibc, aside from being a more readable and cleaner codebase). And musl has done a lot of work to have correct cross-platform implementations. Granted whenever Rust adds a new target, it should be easier for things to "just work" when cross-compiled, but Rust is far less portable than C + a modicum of macros at the moment.
