We then discussed a bunch of options, talked about `Symbol::libraryLookup` and verified that this lookup allows to load libraries as expected in AIX. There's some jextract issues which need to be worked out, but that's outside the scope of this PR.

My conclusion was that, given that in this case we needed a fully versioned archive member, it is hard to implement and/or to expose as a simple `mapLibraryName` add-on. Is that correct?

I Feel it is good to at least keep the option for Java developers to use system.load for member objects. 
Also , the original intention of the PR was to allow .so to .a mapping if .so is not there. This fix had gone into J9 and I think it would be good to keep this support in OpenJDK too. 
In summary, the functionality to parse members can be kept limited to System.load and the deterministic .so to .a mapping as part of System.loadLibrary().
