| # Creates a symlink from root_build_dir/target_name to |binary_label|. This rule |
| # is meant to be used within if (current_toolchain == default_toolchain) blocks |
| # and point to targets in the non-default toolchain. |
| # Note that for executables, using a copy (as opposed to a symlink) does not |
| # work when is_component_build=true, since dependent libraries are found via |
| # relative location. |

| # Example: |
| # if (current_toolchain == host_toolchain) { |
| # executable("foo") { ... } |
| # } else if (current_toolchain == default_toolchain) { |
| # binary_symlink("foo") { |
