cmd/go: invalid flag when importing bimg

[tssajo]

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

# go version
go version go1.11 linux/amd64

Does this issue reproduce with the latest release?

Yes, and I can reproduce the issue with Go 1.10.x too.
However the build works just fine with Go 1.9.6 on an Ubuntu 14.04 system.

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

# lsb_release -a
Distributor ID: Debian
Description:    Debian GNU/Linux 8.11 (jessie)
Release:        8.11
Codename:       jessie

What did you do?

Wrote a program using h2non/bimg.v1 that begins like this:

package main

import (
	bimg "gopkg.in/h2non/bimg.v1"
)

and then tried to build it:

go build

What did you expect to see?

A successful build.

What did you see instead?

# go build
go build gopkg.in/h2non/bimg.v1: invalid flag in pkg-config --libs: -Wl,--export-dynamic

Any help would be highly appreciated!

Note: Because of the above issue, I'm stuck with Go 1.9.6 for quiet a while now... :(

@ianlancetaylor looks like another flag to add to the whitelist?

@tssajo As a temporary workaround there is a CGO_LDFLAGS_ALLOW environmental flag which accepts a regex.
