Setting environment variables for go command configuration is too difficult and system-specific. This CL adds go env -w, to change the default settings more easily, in a portable way. It also adds go env -u, to unset those changes. See https://golang.org/design/30411-env for details. Fixes #30411.

|
# GOROOT_FINAL: The expected final Go root, baked into binaries.
|
|
# The default is the location of the Go tree during the build.
|
|
#
|
|
# GOHOSTARCH: The architecture for host tools (compilers and
|
|
# binaries). 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.
