[pkg-go] Bug#827426: golang-golang-x-tools: stringer is broken

[Eric Cooper]

Package: golang-golang-x-tools
Version: 1:0.0~git20160315.0.f42ec61-2
Severity: important

The stringer program no longer understands how to import standard Go
packages.  For example, running "stringer -type=MyType foo.go" on the following
foo.go file:
----
    package main

    import (
	    "fmt"
    )

    type MyType int

    //go:generate stringer -type=MyType

    const (
	    Alpha MyType = 1
	    Beta MyType = 1
	    Gamma MyType = 1
    )

    func main() {
	    fmt.Println(Alpha)
    }
----

produces the error:
    stringer: checking package: foo.go:4:2: could not import fmt (can't find import: )

Running strace shows that it's looking here:
    /usr/lib/go/pkg/linux_amd64/fmt.a
But the current golang system has it here:
    /usr/lib/go-1.6/pkg/linux_amd64/fmt.a

And indeed, when I removed /usr/lib/go and symlinked it to
/usr/lib/go-1.6 instead, stringer worked correctly.  But I'm not sure
if that simple fix breaks anything else ...
