[Docker-maint] Bug#818651: golang: cannot use net package without CGO

[Ayke van Laethem]

Package: golang
Version: 2:1.6-1
Severity: normal

Dear Maintainer,

Golang 1.3 (jessie) can build this file just fine without CGO, but golang 1.5
and 1.6 throws an error:

    package main

    import (
        "fmt"
        "net"
    )

    func main() {
        fmt.Println("HostPort:", net.JoinHostPort("google.com", "80"))
    }

To reproduce, compile this with the environment variable CGO_ENABLED=0. It
fails with golang 1.5 (jessie-backports) and golang 1.6 (testing) but succeeds
in golang 1.3 (jessie).
The exact (but cryptic) error reported is:

    go install net: open /usr/lib/go/pkg/linux_amd64/net.a: permission denied

Since Go 1.2 (according to the docs [1]) it should be possible to use the net
package without CGO on some systems.
My system is linux-amd64 (one with jessie and one with testing).
