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

$ go version
go version devel +700575be81 Thu Nov 15 21:51:50 2018 +0000 linux/amd64

Does this issue reproduce with the latest release?

This reproduces from commit 700575b onward (and doesn't seem to be being picked up by the builders, perhaps because none of them have SWIG installed).

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

go env Output
$ go env

What did you do?

Since commit 700575b, building Go git tip from source fails with an error in the SWIG tests:

##### ../misc/swig/callback
# _/data/code/go-lang/go/misc/swig/callback
vet: $WORK/b050/_cgo_gotypes.go:7:8: could not import unsafe (can't resolve import "")
FAIL    _/data/code/go-lang/go/misc/swig/callback [build failed]
2018/11/16 11:31:28 Failed: exit status 2

I also have gcc-go installed on this system, in case it makes a difference in SWIG's behavior. This is a Fedora 28 system with swig-3.0.12-17.fc28.x86_64, but I see the same build failure on Ubuntu 18.04 with their version of SWIG. As expected, Go builds on an Ubuntu 18.04 machine that doesn't have SWIG installed.
