I came to the same conclusion when I tried to bisect the git repo
between 3.0.2 and 3.0.3 on my powerpc machine. By reverting that commit
I was able to build 44ad8fbde55df452ac1c88427662403e7af5b9bb (3.0.2-70,
6 commit later) but wasn't able to build 3.0.3. I started the build
without any precompiled bootstrap .go files.
