5 :: Environment variables that control make.bat:
7 :: GOROOT_FINAL: The expected final Go root, baked into binaries.
8 :: The default is the location of the Go tree during the build.
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.
15 :: GOARCH: The target architecture for installed packages and tools.
17 :: GOOS: The target operating system for installed packages and tools.
19 :: GO_GCFLAGS: Additional go tool compile arguments to use when
20 :: building the packages and commands.
22 :: GO_LDFLAGS: Additional go tool link arguments to use when
23 :: building the commands.
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.
29 :: CC: Command line to run to compile C code for GOHOSTARCH.
32 :: CC_FOR_TARGET: Command line to run compile C code for GOARCH.
33 :: This is used by cgo. Default is CC.
35 :: FC: Command line to run to compile Fortran code.
36 :: This is used by cgo. Default is "gfortran".
40 :: Keep environment variables within this script
41 :: unless invoked with --no-local.
