Description

When I use the builder, crates that contain Rust-compiled C++ code fail to link. Example:

...much spew...
  = note: ld: archive has no table of contents file '/root/src/difft/target/aarch64-apple-darwin/release/build/difftastic-abae5b1432a24d5f/out/libtree-sitter-ada.a' for architecture arm64
          clang: error: linker command failed with exit code 1 (use -v to see invocation)
...much spew...

AFAIK: lib tree-sitter-ada.a is built from C++ code by the difftastic crate.

This is working as intended? Or am I being an idiot?

Contributor guide

Research direction
Check if the osxcross toolchain includes C++ libraries and ensure that the Rust target correctly links against them. Also verify that the CXX toolchain is properly configured.
