     6  # Environment variables that control make.rc:
     7  #
     8  # GOROOT_FINAL: The expected final Go root, baked into binaries.
     9  # The default is the location of the Go tree during the build.
    10  #
    11  # GOHOSTARCH: The architecture for host tools (compilers and
    12  # binaries).  Binaries of this type must be executable on the current
    13  # system, so the only common reason to set this is to set
    14  # GOHOSTARCH=386 on an amd64 machine.
    15  #
    16  # GOARCH: The target architecture for installed packages and tools.
    17  #
    18  # GOOS: The target operating system for installed packages and tools.
    19  #
    20  # GO_GCFLAGS: Additional 5g/6g/8g arguments to use when
    21  # building the packages and commands.
    22  #
    23  # GO_LDFLAGS: Additional 5l/6l/8l arguments to use when
    24  # building the commands.
    25  #
    26  # GO_CCFLAGS: Additional 5c/6c/8c arguments to use when
    27  # building.
    28  #
    29  # CGO_ENABLED: Controls cgo usage during the build. Set it to 1
    30  # to include all cgo related files, .c and .go file with "cgo"
    31  # build directive, in the build. Set it to 0 to ignore them.
