Comment (by leonardo.schenkel@…):

 I fixed it in my local environment in a different way: I upgraded Go to
 1.7.1 and bootstrapped it with itself (although that works with 1.7.0 was
 well). Go 1.4 is officially used by upstream to bootstrap Go since they
 want to prevent newer versions depending on Go features introduced after
 1.4, however that is less important for downstream users — and this has
 the advantage of not requiring download/building Go 1.4 which results in
 faster builds. This was the same approach taken by Homebrew as well, since
 the fix for a change of gettimeofday(2) introduced in OS X 10.12 is not
 backported to 1.4 yet. I have attached my updated Portfile.
