dist: Show warning building out-of-date packages in 'go test -race'

[dlintw]

What steps will reproduce the problem?
If possible, include a link to a program on play.golang.org.
1. build by this PKGBUILD script, (eg. build multiple GOARCH GOOS)
  https://aur.archlinux.org/packages/go/go-crosstool/PKGBUILD
2. go test works.
3. go test -race occurs

I'm try to build Go package for Arch Linux, but wonder what's the correct steps to build
'test -race' support.

In the PKGBUILD script, I just call "make.bash --noclean"
But, there is no usr/lib/go/pkg/linux_amd64_race/ directory.

What is the expected output?


What do you see instead?

$ go test -race
warning: building out-of-date packages:
    runtime
    runtime/cgo
        ... omit ..
    regexp/syntax
    regexp
installing these packages with 'go test -race -i' will speed future tests.

$ GOPATH=/home/USER/go
$ go test -race -i

go install runtime: mkdir /usr/lib/go/pkg/linux_amd64_race/: permission denied

Which compiler are you using (5g, 6g, 8g, gccgo)?
x86_64

Which operating system are you using?
Arch Linux x86_64

Which version are you using?  (run 'go version')
go version go1.1 linux/amd64

Please provide any additional information below.

Comment 2:

go build -race std
should do it.
Not really an issue, just a help request.

Status changed to Invalid.

Comment 3:

You probably want
go install -race std
but you get the idea.
