The Mac reverse buildlets are now saying:

Oh, because of snapshots.

The GOROOT is baked into the binaries at one location, and then another machine runs tests and the GOROOT is wrong.

I remember hitting this with the Scaleway ARM builders too but eventually just sidestepped the issue by making the directory to always be /workdir.

I'll see if I can fix it better here.
