 I haven't seen this error through many builds that included golang.
 However I have only tried building on Ubuntu 12.04.

 I found some references to the "bits/predefs.h" error:
  *
 http://blog.riff.org/2014_06_06_what_to_do_when_go_will_not_run_nor_install_from_source
  * https://ubuntuforums.org/showthread.php?t=1877944
  * https://lists.debian.org/debian-glibc/2013/08/msg00030.html
  * https://github.com/gogits/gogs/issues/93

 The sources say to try installing either libc6-dev-i386 or gcc-multilib.
 What does `apt-get build-dep golang` say inside the VM? It could be that
 we just need to add a new dependency in the descriptor.
