With the current vendoring process, any Cargo build emits the following warning: warning: `.../.cargo/config` is deprecated in favor of `config.toml` .cargo/config.toml was introduced in 1.39 [1], so there shouldn't be backwards compatibility issues in Buildroot. However, because the generated config file becomes part of the vendored archive, this changes the hashes of all Cargo-based packages.
