Hello Mandy,

> One idea to fix this is to extend jlink --dedup-legal-notices to accept an option that specify the module names that always wants to keep a copy of the legal files.

That sounds reasonable. So `jdk.javadoc` through of build system could then be marked as requiring a copy of these legal notice files when the JDK image is being built. 
Do you think that the option should be applicable only on systems where symbolic link isn't applicable or should the `LegalNoticeFilePlugin` use that option to just create copies of the legal files for a chosen module, irrespective of which platform it is for?
