716 This adds a -jX option to certain packages that are known to
717 behave well for parallel build. By default the package make processes
718 use the main jobserver, in which case this option only takes effect

729 This passes the main make process jobserver fds to package builds,

732 Note that disabling this may overcommit CPU resources depending on the
733 -j level of the main make process, the number of package
734 submake jobs selected below and the number of actual CPUs present.
735 Example: If the main make is passed a -j4 and the submake -j
