Usage: $ME [-h]
$ME [-c <commit>] [-v] [-m <val>] [-j <val>] [-t <val>] [-i <image-name>] [-d <path>]
Options:
-h
Display this help and exit.
-c <commit>
git checkout <commit> before anything else
-v
Show bitbake output, don't redirect it to a log.
-m <machine>
Value for MACHINE. Default is qemux86.
-j <val>
Value for PARALLEL_MAKE. Default is 8.
-t <val>
Value for BB_NUMBER_THREADS. Default is 8.
-i <image-name>
Instead of timing against core-image-sato, use <image-name>
-d <path>
Use <path> as DL_DIR
-p <githash>
Cherry pick githash onto the commit
Note: current working directory must be inside a poky git clone.

# - collect data
# Part2:
# - bitbake virtual/kernel -c cleansstate
# - time bitbake virtual/kernel
# Part3:
# - add INHERIT to local.conf
# - clean build dir
# - build
# - report size, remove INHERIT
