Cross compile failure

Cross compile failure

vendor/github.com/siddontang/go-mysql/client/auth.go:11:2: 
    build constraints exclude all Go files in .../vendor/github.com/go-mysql/packet
make: *** [searcher] Error 1

Build under go version go1.10.4 darwin/amd64 with GOOS=linux.

Since the packet package (and others) imports "C":

https://github.com/siddontang/go-mysql/blob/master/packet/conn.go#L1-L8

package packet

import "C"
import (
	"bytes"
	"io"
	"net"
...

And cgo is disabled with cross compile, see golang/go#24068

Enable CGO via CGO_ENABLED=1 cannot help.

So, is there any way to pass this compile failure? (Do not want to build under docker cause of the build cache.)

Or give an explaination in README to inform others.

Thanks.
