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

- If you are unsure, select N.

- This passes the main make process jobserver fds to package builds,
- enabling full parallelization across different packages.
-
- Note that disabling this may overcommit CPU resources depending on the
- -j level of the main make process, the number of package submake jobs
- selected below and the number of actual CPUs present.
- Example: If the main make is passed a -j4 and the submake -j
- is also set to 4, we may end up with 16 parallel make processes
- in the worst case.

- WARNING: This may break build or kill your cat, as it builds packages

- Only say Y if you don't mind fixing broken packages. Before reporting
- build bugs, set this to N and re-run the build.
