Description:

Go's race detector (http://blog.golang.org/race-detector)
Additional info:
* go 2:1.4.2-1


Steps to reproduce:
1. Install go
2. Acquire minimal example file below
3. Run `go install -race` on the package/file
4. Observe "go install os/signal: open /usr/lib/go/pkg/linux_amd64_race/os/signal.a: permission denied"

Should be noted that the equivalent file in /usr/lib/go/pkg/linux_amd64/os/signal.a exists fine
and that doing this with sudo works fine, "installing" the correct files


Minimal file:

package main

import "log"
import "os"
import "os/signal"

func main() {
log.Println("Hello!")
var c chan<- os.Signal
signal.Stop(c)
}
