290 This adds a -jX option to certain packages that are known to
291 behave well for parallel build.
292
293 Note that this may overcommit CPU resources depending on the
294 -j level of the main make process, the number of package
295 submake jobs selected below and the number of actual CPUs present.
296 Example: If the main make is passed a -j4 and the submake -j
297 is also set to 4, we may end up with 16 parallel make processes
298 in the worst case.
299
300 You get maximum build performance, if you set the package build
301 jobs to the number of CPUs (cores) available and also start the main
302 make process with -jX, where X is the number of CPUs (cores).
303 However, make sure you have enough RAM available for
304 NR_CPUS to the power of two (NR_CPUS^2) make jobs.
