When there isn't a version-script for a shared library (like for unstable libs), we create one based on the current Xen version. But that version-script became out-of-date as soon as Xen's version changes and make as no way to regenerate the version-script on rebuild. For unstable libs, we only needs the symver to be different from a previous release of Xen. There's an option "--default-symver" which allow to use the soname as symver and as the soname have the Xen release version, it will be different for every release. With --default-symver we don't need to generate a version-script. But we also need to know if there's already an existing version script , for that we introduce $(version-script) to be used to point to the path of the existing script. (Guessing if a version script exist for a stable library with for example $(wildcard) won't work as a file will exist when building the library without this patch.) We don't need the version-script unless we are making the shared library so it is removed from the "all" target.
