# Pull and run op-build.
# Some Notes:
#  - If using a preexisting source tree, make sure op-build-env exists
#       at the root. The cloning logic uses that to determing whether or not
#       to pull a fresh copy
#
#  - Determining if a defconfig has already been set is done by checking if
#       /op-build/output/.config exists. Usually this should not be a problem
