Previously the extra m needed for cgo callbacks was created on the first callback. This works for cgo, however the cgocallback mechanism is also borrowed by badsignal which can run before any cgo calls are made. Now we initialize the extra M at runtime startup before any signal handlers are registered, so badsignal cannot be called until the extra M is ready. Updates #10207.

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.
