Go test complains gcc is missing when importing net/http

[palsivertsen]

What version of Go are you using (go version)?

Tested using the docker image golang:1-alpine (233ed4ed14bf)

/go/src/foo # go version
go version go1.11 linux/amd64

Does this issue reproduce with the latest release?

Yes go1.11

What operating system and processor architecture are you using (go env)?

/go/src/foo # go env
GOARCH="amd64"
GOBIN=""
GOCACHE="/root/.cache/go-build"
GOEXE=""
GOFLAGS=""

What did you do?

Create project foo
Add file bar.go

package main

import  _ "net/http"

Other imports would probably give similar results.

What did you expect to see?

/go/src/foo # go test ./...
?   	foo	[no test files]

What did you see instead?

/go/src/foo # go test ./...
# runtime/cgo
exec: "gcc": executable file not found in $PATH

I'm going to close this as a dup of #27303 (as you mention), #26988 and/or #27285. Please comment if you disagree.
