+Subject: [PATCH] remove dependency check on version file
+
+$(VERSION_DEPS) includes dependencies from tzdata meaning applications
+such as zic can't build from tzcode on their own.  Remove the dependency
+to $(VERSION_DEPS) since it is not necessary to check for version updates
+in released code.  This solves building zic from tzcode without needing
+tzdata.
