+ 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.
