In external linking mode, the linker automatically imports runtime/cgo. When the user uses non-standard compilation options, they have to know to run go install runtime/cgo. When the go tool adds non-standard compilation options itself, we can't force the user to do that. So add the dependency ourselves. Bad news: we don't currently have a clean way to know whether we are going to use external linking mode. This CL duplicates logic split between cmd/6l and cmd/internal/ld. Good news: adding an unnecessary dependency on runtime/cgo does no real harm. We aren't going to force the linker to pull it in, we're just going to build it so that its available if the linker wants it.

Binary Distribution Notes
If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:
export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin
See https://golang.org/doc/install or doc/install.html for more details.
