I am trying to cross-compile to target x86_64-unknown-linux-musl , however it fails with

   Compiling tree-sitter v0.25.1
error: failed to run custom build command for `tree-sitter-rust v0.23.2`

Caused by:
  process didn't exit successfully: `/home/xxx/analyzer/target/release/build/tree-sitter-rust-e81771346d0450b6/build-script-build` (exit status: 1)

I tried to install musl-tools and musl-dev on Ubuntu, however I only have x86_64-linux-musl-gcc , musl-gcc and musl-ldd available. Where can I find musl specific binutils?
