Yes, this works and is the easier of the two methods.  Using a desktop OS
and starting no Go compilers:

1. download the Go 1.6 binaries for your desktop OS and install them; set
GOROOT_BOOTSTRAP to that directory (e.g. /usr/local/go)

2. copy the Go 1.6 sources (either the tar.gz or git clone of sources) to
your desktop OS; set GOROOT to that directory (e.g. $HOME/go)

3. build the bootstrap for Plan 9 (i.e. go-plan9-386-bootstrap.tbz) on your
desktop:
        $ cd $GOROOT/src
        $ GOOS=plan9 GOARCH=386 ./bootstrap.bash
   if all is well, this will produce ../../go-plan9-386-bootstrap.tbz

4. untar this in your Plan 9 environment and set GOROOT_BOOTSTRAP to that
directory; e.g. drawterm from your desktop OS to Plan 9:
        % cd $home
        % bunzip2 -c /mnt/term/path-to-go-plan9-386-bootstrap.tbz | tar -xv
        % GOROOT_BOOTSTRAP=$home/go-plan9-386-bootstrap

5. copy Go 1.6 sources to your Plan 9 fs and set GOROOT to that directory;
e.g. drawterm from your desktop OS to Plan 9:
        % mkdir $home/go
        % dircp /mnt/term/path-of-GOROOT-on-desktop $home/go
        % GOROOT=$home/go
        % cd $GOROOT/src
        % ./all.rc

If you run Plan 9 in a VM, emulator or a confined device (RPi), it will be
easier/faster to cross compile your app and copy it over. E.g. to compile
for 9Pi:
        $ GOOS=plan9 GOARCH=arm go build
