+Failed Generating Licensing for ${PKG}
+Note that many/most open source licenses require that you distribute the license
+with the code, therefore you should fix this instead of overridding this check.
+
+Note too that you need to bundle the license with binary packages too, even
+if they are not part of ChromeOS proper since all packages are available as
+prebuilts to anyone and therefore must include a license.
+
+If you need help resolving the licensing error you just got, please have a
+look at
