#   - all (default) - builds all targets and runs all non-integration tests/checks
#   - basic-checks - performs basic checks like license, spelling, trailing spaces and linter
#   - check-deps - check for vendored dependencies that are no longer used
#   - checks - runs all non-integration tests/checks
#   - clean-all - superset of 'clean' that also removes persistent state
#   - clean - cleans the build area
#   - configtxgen - builds a native configtxgen binary
#   - configtxlator - builds a native configtxlator binary
#   - cryptogen - builds a native cryptogen binary
#   - desk-check - runs linters and verify to test changed packages
#   - dist-clean - clean release packages for all target platforms
#   - docker[-clean] - ensures all docker images are available[/cleaned]
#   - docker-list - generates a list of docker images that 'make docker' produces
#   - docker-tag-latest - re-tags the images made by 'make docker' with the :latest tag
#   - docker-tag-stable - re-tags the images made by 'make docker' with the :stable tag
#   - docker-thirdparty - pulls thirdparty images (kafka,zookeeper,couchdb)
#   - gotools - installs go tools like golint
#   - help-docs - generate the command reference docs
#   - idemixgen - builds a native idemixgen binary
#   - integration-test-prereqs - setup prerequisites for integration tests
#   - integration-test - runs the integration tests
#   - license - checks go source files for Apache license header
#   - linter - runs all code checks
#   - native - ensures all native binaries are available
#   - orderer - builds a native fabric orderer binary
#   - orderer-docker[-clean] - ensures the orderer container is available[/cleaned]
#   - peer - builds a native fabric peer binary
#   - peer-docker[-clean] - ensures the peer container is available[/cleaned]
#   - profile - runs unit tests for all packages in coverprofile mode (slow)
#   - protos - generate all protobuf artifacts based on .proto files
#   - publish-images - publishes release docker images to nexus3 or docker hub.
#   - release-all - builds release packages for all target platforms
#   - release - builds release packages for the host platform
#   - tools-docker[-clean] - ensures the tools container is available[/cleaned]
#   - unit-test-clean - cleans unit test state (particularly from docker)
#   - unit-test - runs the go-test based unit tests
#   - verify - runs unit tests for only the changed package tree
