Rustc stripping broken on 1.83.0

[deciduously]

Compiling rust programs is failing unless strip = false due to a hardcoded dependency on /usr/bin/strip

[deciduously]

Here's the problematic line in rustc: https://github.com/rust-lang/rust/blob/90b35a6239c3d8bdabc530a6a0816f7ff89a0aaf/compiler/rustc_codegen_ssa/src/back/link.rs#L1092

    if sess.target.is_like_osx {
        // Use system `strip` when running on host macOS.
        // <https://github.com/rust-lang/rust/pull/130781>
        let stripcmd = if cfg!(target_os = "macos") { "/usr/bin/strip" } else { "strip" };

If the host and target are both macOS, on 1.83.0 this path is hardcoded.

[deciduously]

This is fixed as of 1.84.0: rust-lang/rust#131405

The rust toolchain will ship rust-objcopy from LLVM and use that for stripping. This has already been merged to master and is slated for the 1.84 milestone.
