The 'lib' target was inteded to be a target the project-specific build could override. However, the common build was using it to create dependancies on '-lib-local' and '-lib-ivy'. If a project-specific build ovverrode lib and forgot to add those dependancies it would break. The project-specific builds should not be required to know about the internal dependancies of the common build. A new target '-lib' was created, which depends on '-lib-local', 'lic-ivy', and 'lib'. 'lib' is not an empty target that is safe to be overridden.
