A package builds with -j1 unless it sets PKG_BUILD_PARALLEL, and 171 of the 220 packages do not set it. These three gain the most from the job server on a cold build of this tree: mtd-utils 24.77 s -> 6.43 s libsepol 17.99 s -> 2.18 s libselinux 7.82 s -> 1.89 s mtd-utils runs while nothing else does, so its 18 s count against the wall clock in full. Each one builds three times out of three with the job server, and each build writes a tree that is identical to the one a serial build writes. nftables gains as well, 17.9 s to 13.0 s, but it is left alone: its build directory differs between two serial builds, so the check that covers the other three says nothing about it.
