It would seem the tar name is not the parent bset.

That implies the tools are arch specific and they are not. The tools should be
tagged with the host arch details if we add anything.

Yeap.

Correct.

Packaging is beyond the RSB. You have highlighted a couple of issues and more
exist. For example in each build of gcc there are common host files and there
are common host independent files. To map multiple builds of tools into a
packaging system you need to identify all common pieces and then group them
based on the packaging system requirements. You then create a package dependency
tree for the generated packages.
