Binaries of this type must be executable on the current :: system, so the only common reason to set this is to set :: GOHOSTARCH=386 on an amd64 machine. :: :: GOARCH: The target architecture for installed packages and tools. :: :: GOOS: The target operating system for installed packages and tools. :: :: GO_GCFLAGS: Additional go tool compile arguments to use when :: building the packages and commands. :: :: GO_LDFLAGS: Additional go tool link arguments to use when :: building the commands. :: :: CGO_ENABLED: Controls cgo usage during the build. Set it to 1 :: to include all cgo related files, .c and .go file with "cgo" :: build directive, in the build. Set it to 0 to ignore them. :: :: CC: Command line to run to compile C code for GOHOSTARCH. :: Default is "gcc". :: :: CC_FOR_TARGET: Command line to run compile C code for GOARCH. :: This is used by cgo. Default is CC. :: :: FC: Command line to run to compile Fortran code. :: This is used by cgo.
