```
$ CGO_ENABLED=0 go install -a std
go install runtime: open /usr/lib/go/pkg/linux_amd64/runtime.a: permission denied
```

This is what I get when I run that without permission to write to /usr/lib (sorry, was mistaken about /usr/share) - that tries to write the compiled versions directly into GOROOT instead of just in the GOPATH, which is undesirable.  I would love to try to help debug "go build -a" if I can, since that's what we've had to do to fix this in the Gentoo ebuild (and I've verified that our resulting binary is successfully statically compiled).
