### What did you do?

I tried to compile the following:

package main

import _ "golang.org/x/sys/cpu"

func main() {}

What did you expect to see?

The compile should be successful.

What did you see instead?

$ go build
# golang.org/x/sys/cpu
../go/src/golang.org/x/sys/cpu/cpu_x86.go:9:23: cacheLineSize redeclared in this block
	previous declaration at ../go/src/golang.org/x/sys/cpu/cpu_wasm.go:11:23
