[versioning=yes]: Build the mapfiles with a pattern rule that lists all of them as targets. (sysd-versions): Depend only on Versions.def. Write a Makefile fragment that defines $(vers-libs) based on contents of that file; then include it. (lib-noranlib): Depend on lib-mapfiles not sysd-versions. (lib-mapfiles): New target, depends on sysd-versions and $(vers-libs). Predicate all this on avoid-generated unset as well as versioning.
