go: cmd/link: missing debug_frame section if package plugin is imported

Please answer these questions before submitting your issue. Thanks!

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

go version devel +00587e8 Fri Jan 26 23:55:04 2018 +0000 linux/amd64

but this also happens with the latest release candidate for 1.10.

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

GOARCH="amd64"
GOBIN=""
GOCACHE="/home/a/.cache/go-build"
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/home/a/n/go/"
GORACE=""
GOROOT="/usr/local/go"
GOTMPDIR=""
GOTOOLDIR="/usr/local/go/pkg/tool/linux_amd64"
GCCGO="gccgo"
CC="gcc"
CXX="g++"
CGO_ENABLED="1"
CGO_CFLAGS="-g -O2"
CGO_CPPFLAGS=""
CGO_CXXFLAGS="-g -O2"
CGO_FFLAGS="-g -O2"

GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build091711191=/tmp/go-build -gno-record-gcc-switches"

What did you do?

Compile anything that imports plugin:

package main

import (
	"plugin"
	"fmt"
)

func main() {
	test := plugin.Plugin{}
	fmt.Println(test)
}

The executable used to have .debug_frame in 1.9 but has eh_frame now.

Was this done intentionally?
