up by pk (and fix comments to match): * A .WAIT here means that only the *immediately preceding* target needs to be added to the list of "install-foo" targets used to ensure that dependencies are installed (otherwise much more than is necessary gets installed during the build process, increasing build time here) * If building only an individual target such as "dependall-yacc", the prerequisites may need to be built before running their "install-foo" targets -- so add a dependency in that case on "dependall-foo".
