467 This adds a -jX option to certain packages that are known to

469 use the main jobserver, in which case this option only takes effect

483 Note that disabling this may overcommit CPU resources depending on the
484 -j level of the main make process, the number of package
485 submake jobs selected below and the number of actual CPUs present.
486 Example: If the main make is passed a -j4 and the submake -j
487 is also set to 4, we may end up with 16 parallel make processes

510 packages with multiple jobs that are probably not tested in
511 a parallel build environment.
513 Only say Y, if you don't mind fixing broken packages.
