    # 1) This target needs to be a static_library (not a source set) on Mac to
    #    avoid the build errors in
    #    https://codereview.chromium.org/2779193002#msg82.
    # 2) A static_library must have at least one source file, to avoid build
    #    errors on Mac and Windows. https://crbug.com/710334
    # 3) A static_library with complete_static_lib = true, which would not
    #    require adding the empty file, will result in duplicate symbols on
    #    Android. https://codereview.chromium.org/2852613002/#ps20001
