  #
  # - Make its Rust library available to rustc. This is done by
  #   symlinking all library dependencies into a directory that
  #   can be provided to rustc.
  # - Accumulate linking flags. These flags are largely used for
  #   linking native libraries.
  #
  # The crate link flags are added to the `link` and `link.final`
  # files. The `link` file is used for linkage in the current
  # crate. The `link.final` file will be copied to the output and can
  # be used by downstream crates to get the linker flags of this
