     5  :: Environment variables that control make.bat:
     6  ::
     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 go tool compile arguments to use when
    20  :: building the packages and commands.
    21  ::
    22  :: GO_LDFLAGS: Additional go tool link 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.
    28  ::
    29  :: CC: Command line to run to compile C code for GOHOSTARCH.
    30  :: Default is "gcc".
    31  ::
    32  :: CC_FOR_TARGET: Command line to run compile C code for GOARCH.
    33  :: This is used by cgo. Default is CC.
    34  ::
    35  :: FC: Command line to run to compile Fortran code.
