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.

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.

Always set the default package build rules to parallel build.

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

with multiple jobs that are probably not tested in a parallel build
|
|
environment.
|

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