prompt "Compile certain packages parallelized"

help
This adds a -jX option to certain packages that are known to
behave well for parallel build.
Note that 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.
You get maximum build performance, if you set the package build
jobs to the number of CPUs (cores) available and also start the main
make process with -jX, where X is the number of CPUs (cores).
However, make sure you have enough RAM available for
NR_CPUS to the power of two (NR_CPUS^2) make jobs.
If you are unsure, select N.
