SGTM. This seems somewhat similar in direction as the also very well motivated removal of the @bors r+ |

Remove attribute `#[link_args]` Closes rust-lang#29596 The attribute could always be replaced with `-C link-arg`, but cargo didn't provide a reasonable way to pass such flags to rustc. Now cargo supports `cargo:rustc-link-arg*` directives in build scripts (https://doc.rust-lang.org/cargo/reference/unstable.html#extra-link-arg), so this attribute can be removed.

With this removal it's now impossible to pass different link_args to different binaries within the same crate. Is there some workaround for this? |

Add `cargo:rustc-link-arg-bin` flag. This PR implements a `cargo:rustc-link-arg-bin` command to specify per-binary link args from build scripts. This follows the suggestion from the tracking issue #9426. Syntax is `cargo:rustc-link-arg-bin=BIN_NAME=ARG` This was previously possible to do using the `#[link_args=".."]` attribute, but it was removed in rust-lang/rust#83820 in favor of the Cargo extra-link-args feature, which can currently not specify different link args for different bins in the same crate. This PR adds back the ability to do that.
