     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	::

    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.
