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

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.

Before reporting build bugs, set this to N and re-run the build.
