// Encodes device link arguments as `links` metadata: a count key plus
// one key per argument, indexed from zero, rather than one joined
// string. A joined value needs a parser on the reading side to survive
// a BELA_SYSROOT containing whitespace; a count and separate keys need
// none. See docs/cross-compile.md for the two crates that read this.
//
// Included by build.rs, where it runs, and by src/lib.rs under
// cfg(test) — the same split shim_compiler.rs uses, because a build
// script is not a target `cargo test` builds.
