Several lines below, there's "Approximate times" section, telling 
someone's experience with some unspecified repo revision, which took 1.5 
hrs. I can tell you that I used to have ~8 hrs build time on Kaveri 7700 
box with spinning HDD.

You should expect long build times on your laptop. But if you also are 
going to do other tasks on it during the build (to increase build times 
even more), then you may adjust it using --with-parallelism (discussed 
there), which defaults to use all your cores, but which you could want 
to set to a lower value to free some resources; or you may run make 
using nice (`nice make`) to decrease its priority and make system 
responsive to interaction without sacrificing cores.
