     8  # Environment variables that control make.bash:
     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  # GO_EXTLINK_ENABLED: Set to 1 to invoke the host linker when building
    30  # packages that use cgo.  Set to 0 to do all linking internally.  This
    31  # controls the default behavior of the linker's -linkmode option.  The
    32  # default value depends on the system.
    33  #
    34  # GO_LDSO: Sets the default dynamic linker/loader (ld.so) to be used
    35  # by the internal linker.
    36  #
    37  # CC: Command line to run to compile C code for GOHOSTARCH.
    38  # Default is "gcc". Also supported: "clang".
    39  #
    40  # CC_FOR_TARGET: Command line to run to compile C code for GOARCH.
    41  # This is used by cgo. Default is CC.
    42  #
    43  # CC_FOR_${GOOS}_${GOARCH}: Command line to run to compile C code for specified ${GOOS} and ${GOARCH}.
    44  # (for example, CC_FOR_linux_arm)
    45  # If this is not set, the build will use CC_FOR_TARGET if appropriate, or CC.
    46  #
    47  # CXX_FOR_TARGET: Command line to run to compile C++ code for GOARCH.
    48  # This is used by cgo. Default is CXX, or, if that is not set,
    49  # "g++" or "clang++".
    50  #
    51  # CXX_FOR_${GOOS}_${GOARCH}: Command line to run to compile C++ code for specified ${GOOS} and ${GOARCH}.
    52  # (for example, CXX_FOR_linux_arm)
    53  # If this is not set, the build will use CXX_FOR_TARGET if appropriate, or CXX.
    54  #
    55  # FC: Command line to run to compile Fortran code for GOARCH.
    56  # This is used by cgo. Default is "gfortran".
    57  #
    58  # PKG_CONFIG: Path to pkg-config tool. Default is "pkg-config".
    59  #
    60  # GO_DISTFLAGS: extra flags to provide to "dist bootstrap".
    61  # (Or just pass them to the make.bash command line.)
    62  #
    63  # GOBUILDTIMELOGFILE: If set, make.bash and all.bash write
    64  # timing information to this file. Useful for profiling where the
    65  # time goes when these scripts run.
    66  #
    67  # GOROOT_BOOTSTRAP: A working Go tree >= Go 1.20.6 for bootstrap.
    68  # If $GOROOT_BOOTSTRAP/bin/go is missing, $(go env GOROOT) is
    69  # tried for all "go" in $PATH. By default, one of $HOME/go1.20.6,
