  You can approximate the overhead with 'make -qp > /dev/null'. 
Everything else that actually does get executed is necessary. Oh, wait: 
the time of dependencies.sh should also be taken along. But basically, 
the Buildroot overhead is roughly 5 seconds.

  Of course, with manually typing commands, you can make some shortcuts, 
like not using 'find' to find which things to remove in the finalize 
steps. On my allpackageyesconfig setup the finalize step takes in the 
order of 30 seconds.
