bazel --ignore_all_rc_files build //...

shows

    Action src/file1_output; 2s linux-sandbox
    Action src/file1_output [for tool]; 2s linux-sandbox

Since the target and exec platforms are identical, I would expect the actions to not be duplicated "[for tool]"

Should I just be using cfg = "target" everywhere instead?
