Speed up "make" with "make -j 8"

[ethaniel]

Perhaps it makes sense to add to the manual that using "make -j 8" (or the number of cores that your CPU has) speeds up the build process?

[cizekmilan]

maybe, better - more universal is make -j$(nproc)

Building on multiple cores is great if you're cross compiling on a big machine with loads of resources, but on a 4GB Nano it's going to slam performance and probably fail to build because it ran out of resources. -j2 works sometimes on some smaller packages, but in my experience large projects still sometimes run into problems when building natively.
