I have a script shown below that I source. Then, running ./make.bash
in $GOROOT/src will build and install everything. You can also build
tests using the host system's gotest (run with -c flag). I'm disabling
hg because codereview might attempt to run Plan 9's gofmt, etc, which
won't work and mess up your CL. More details about the environment
variables are here: http://golang.org/doc/install.html#environment
