//! Build script for xmtp-cli.
//!
//! Emits platform-specific linker flags to suppress duplicate Rust runtime
//! symbols (e.g. `rust_eh_personality`) that arise from statically linking
//! the `libxmtp_ffi` Rust staticlib into another Rust binary.
//!
//! This is necessary for `cargo install xmtp-cli` to work, since the
//! workspace `.cargo/config.toml` is not available outside the workspace.
