An alternative to building a Go 1.4.3 bootstrap environment, is to build a
Go 1.7 bootstrap environment for Plan 9 in a mainstream environment like
Linux or Mac OS X, then use it to build Go 1.7 on Plan 9.   General outline
is to:

* follow the instructions on how to clone and build Go 1.7 on, say, Linux.
* once Go is built  and installed, build a Plan 9 bootstrap
    cd $GOROOT/src
    GOOS=plan9 GOARCH=386 ./boostrap.bash

this produces the bootstrap hierarchy in ../../go-plan9-386-bootstrap.
 copy the hierarchy over to Plan  9 and set GOROOT_BOOTSTRAP to that
location, then build Go 1.7 on Plan 9.

The general explanation of bootstrapping Go is here:
https://golang.org/doc/install/source#go14

FYI, when i need to 'git clone' something on Plan 9, I mount the fs from
Linux (p9p) and do the git stuff there.
