	BuildRace              bool               // -race flag
	BuildToolexec          []string           // -toolexec flag
	BuildToolchainName     string
	BuildToolchainCompiler func() string
	BuildToolchainLinker   func() string

	BuildWork              bool // -work flag
	BuildX                 bool // -x flag
)

These are general "build flags" used by build and other commands. 

var (
	Goarch    = BuildContext.GOARCH
	Goos      = BuildContext.GOOS
	ExeSuffix string
	Gopath    = filepath.SplitList(BuildContext.GOPATH)
)

Global build parameters (used during package load) 

var (
	GOROOT    = findGOROOT()
	GOBIN     = os.Getenv("GOBIN")
	GOROOTbin = filepath.Join(GOROOT, "bin")
	GOROOTpkg = filepath.Join(GOROOT, "pkg")
	GOROOTsrc = filepath.Join(GOROOT, "src")

	// Used in envcmd.MkEnv and build ID computations.
	GOARM = fmt.Sprint(objabi.GOARM)
	GO386 = objabi.GO386
)
var CmdEnv []EnvVar

CmdEnv is the new environment for running go tool commands. User binaries (during go test or go run) are run with OrigEnv, not CmdEnv.
