## Wrapper for starting make inside sonic-slave container
#
#  Supported parameters:
#
#  * PLATFORM: Specific platform we wish to build images for.
#  * BUILD_NUMBER: Desired version-number to pass to the building-system.
#  * ENABLE_DHCP_GRAPH_SERVICE: Enables get-graph service to fetch minigraph files
#    through http.
#  * ENABLE_ZTP: Enables zero touch provisioning.
#  * SHUTDOWN_BGP_ON_START: Sets admin-down state for all bgp peerings after restart.
#  * INCLUDE_KUBERNETES: Allows including Kubernetes
#  * INCLUDE_KUBERNETES_MASTER: Allows including Kubernetes master
#  * INCLUDE_MUX: Include MUX feature/services for TOR switch.
#  * ENABLE_PFCWD_ON_START: Enable PFC Watchdog (PFCWD) on server-facing ports
#  * by default for TOR switch.
#  * ENABLE_SYNCD_RPC: Enables rpc-based syncd builds.
#  * INSTALL_DEBUG_TOOLS: Install debug tools and debug symbol packages.
#  * USERNAME: Desired username -- default at rules/config
#  * PASSWORD: Desired password -- default at rules/config
#  * KEEP_SLAVE_ON: Keeps slave container up and active after building process concludes.
#  *                Note that rm=true is still set, so once user quits from the docker
#  *                           session, the docker will be removed.
#  *                Please note that with current Stretch build structure,
#  *                user of KEEP_SLAVE_ON feature will have to be conscious
#  *                about which docker to stay inside after build is done.
#  *                - If user desires to stay inside Jessie docker, please issue
#  *                  make KEEP_SLAVE_ON=yes jessie
#  *                - If user desires to stay inside Stretch docker, please issue
#  *                  make NOJESSIE=1 KEEP_SLAVE_ON=yes <any target>
#  * SOURCE_FOLDER: host path to be mount as /var/$(USER)/src, only effective when KEEP_SLAVE_ON=yes
#  * SONIC_BUILD_JOBS: Specifying number of concurrent build job(s) to run
#  * VS_PREPARE_MEM: Prepare memory in VS build (drop cache and compact).
#  *                 Default: yes
#  *                 Values:  yes, no
#  * KERNEL_PROCURE_METHOD: Specifying method of obtaining kernel Debian package: download or build
#  * ENABLE_TRANSLIB_WRITE: Enable translib write/config operations via the gNMI interface.
#  *                 Default: unset
#  *                 Values: y
#  * SONIC_DPKG_CACHE_METHOD: Specifying method of obtaining the Debian packages from cache: none or cache
#  * SONIC_DPKG_CACHE_SOURCE: Debian package cache location when cache enabled for debian packages
#  * BUILD_LOG_TIMESTAMP: Set timestamp in the build log (simple/none)
#  * DOCKER_EXTRA_OPTS: Extra command line arguments for dockerd running in slave container.
#  * ENABLE_AUTO_TECH_SUPPORT: Enable the configuration for event-driven techsupport & coredump mgmt feature
#  *                 Default: y
#  *                 Values: y,n
#  * INCLUDE_BOOTCHART: Install SONiC bootchart
#  *                 Default: y
#  *                 Values: y,n
#  * ENABLE_BOOTCHART: Enable SONiC bootchart
