Russ Cox 3ab9ff1107 cmd/go: include Go toolchain information in build ID
This causes packages and binaries built by Go 1.5 to look
out of date to Go 1.6 and vice versa, so that when you flip
between different Go versions but keep the same GOPATH,
the right rebuilding happens at each flip.

Go 1.4 binaries will also look out of date to Go 1.5,
but Go 1.5 binaries will not look out of date to Go 1.4
(since Go 1.4 doesn't have anything like this).
People flipping between Go 1.4 and Go 1.5 will still
need to use go install -a every time to flip to Go 1.4,
but not when they flip back to Go 1.5.

Fixes #6534.
Fixes #10702.

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.
