Arch Linux

Description:
Attempting to build GO packages using `go build --race` results in permission errors as go attempts to build and install missing race libs in stdlib.

# go build mypkg
go install container/heap: open /usr/lib/go/pkg/linux_amd64_race/container/heap.a: permission denied
go install encoding/csv: open /usr/lib/go/pkg/linux_amd64_race/encoding/csv.a: permission denied
go install html: open /usr/lib/go/pkg/linux_amd64_race/html.a: permission denied
go install database/sql/driver: mkdir /usr/lib/go/pkg/linux_amd64_race/database: permission denied
go install expvar: open /usr/lib/go/pkg/linux_amd64_race/expvar.a: permission denied
go install archive/tar: mkdir /usr/lib/go/pkg/linux_amd64_race/archive/: permission denied
go install text/template/parse: mkdir /usr/lib/go/pkg/linux_amd64_race/text/template/: permission denied

The binary package downloadable from https://golang.org/dl/ does not have this issue.
I reported the issue upstream (https://github.com/golang/go/issues/22372) since it looks like the GO package in Arch is built following the official GO build doc, and the response was that the build procedure needs to be updated to include:

go install -race -a std

The response on the upstream issue also indicates other steps need to be taken to get something equivalent to the official binary release, but it was not stated what those steps are.

Additional info:
* package version(s)
1.9.2-2

* config and/or log files etc.


Steps to reproduce:

Try to build the following code with `go build -race`:

package main
import "encoding/csv"
func main() {
csv.NewReader(nil)
}
