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