     7  :: GOROOT_FINAL: The expected final Go root, baked into binaries.
     8  :: The default is the location of the Go tree during the build.
     9  ::
    10  :: GOHOSTARCH: The architecture for host tools (compilers and
    11  :: binaries).  Binaries of this type must be executable on the current
    12  :: system, so the only common reason to set this is to set
    13  :: GOHOSTARCH=386 on an amd64 machine.
    14  ::
    15  :: GOARCH: The target architecture for installed packages and tools.
    16  ::
    17  :: GOOS: The target operating system for installed packages and tools.
    18  ::
    19  :: GO_GCFLAGS: Additional 5g/6g/8g arguments to use when
    20  :: building the packages and commands.
    21  ::
    22  :: GO_LDFLAGS: Additional 5l/6l/8l arguments to use when
    23  :: building the commands.
    24  ::
    25  :: CGO_ENABLED: Controls cgo usage during the build. Set it to 1
    26  :: to include all cgo related files, .c and .go file with "cgo"
    27  :: build directive, in the build. Set it to 0 to ignore them.
