The sysroot install and kernel build targets are time cost, let's use -j<N> to parallelize them with multiple jobs.

This should already work when the users specify -j on the make command line themselves. I'm not a fan of force-enabling it here.
Indeed, we must not do that, because some users might for instance prefer to build multiple archs in parallel and benefit from a better parallelism and now they'd end up with too many processes.
