rules_go: Cross compilation is broken with golang.org/x/sys/unix

I am trying to cross compile to linux binary on darwin_amd64 machine. Compiling to darwin_amd64 target works file, cross compiling to linux_amd64 produces the following error:

bash-3.2$ bazel build //:doit_cross
INFO: Analysed target //:doit_cross (0 packages loaded).
INFO: Found 1 target...
ERROR: /Users/pesterni/go/src/github.com/apesternikov/bazel_go_repr/vendor/golang.org/x/sys/unix/BUILD.bazel:3:1: GoCompile vendor/golang.org/x/sys/unix/linux_amd64_pure_stripped/go_default_library~/partial.a failed (Exit 1)

This problem makes it impossible to build a linux binary (and, consequentially, docker image) referring golang.org/x/sys/unix or any of 2244 packages dependent on it https://godoc.org/golang.org/x/sys/unix?importers. We got this while trying to use github.com/fsnotify/fsnotify.

How to reproduce: clone github.com/apesternikov/bazel_go_repr bazel build //:doit works fine, bazel build //:doit_cross fails. https://github.com/apesternikov/bazel_go_repr/blob/master/BUILD
