Patch merged into coreboot/master: 062e408 build: add what-jenkins-does target

the following patch was just integrated into master:
commit 062e408bc77b935798145e29d4031f8105be5086

build: add what-jenkins-does target

This target does (pretty much) exactly the same what jenkins
    is doing on our build nodes:
     - complete abuild run of our tree with a given payload
     - building all libpayload configs we ship
     - building the cbmem utility

In fact at some point we could tell jenkins to just run this command.

For debugging, pass along V and Q variables so inner make processes
    are slightly more noisy on demand.
