Also builds on recent changes to remove duplicate symbol names. It's good that the PR demonstrates that these can be linked to create "javastatic" but having it copy into the run-time image created by jlink is probably not the eventual outcome.

A possible direction on this is for the build to create a set of packaged modules with the .a files, then have an alternative image builder in jlink that integrates with the native linker. Combined with other parts in Jiangli's slides/proposal, it would mean that jlink could produce a single executable that would work for both the JDK or any set of modules.
