This is stable, right?

Take a look at the PROJECT_CREATE_DEVPKGS/PROJECT_USE_DEVPKGS options. With PROJECT_CREATE_DEVPKGS you get <pkg>->version>-<hash>-dev.tar.gz for most packages. This is the content of <PKG>_PKGDIR. With PROJECT_USE_DEVPKGS you can specify a folder contain such archives. If a matching archive is found, the stages up to install are skipped and the archive is extracted instead. The hash makes sure the sub-options used to create the archive are the correct ones. Note: You cannot use your own packages dir. That introduces really strange circular dependencies.
