Which SSTATE_MIRRORS are you using?

The build logs should show what is being rebuilt. The autobuilder does
reuse sstate during its builds and we'd likely have noticed long build
times if it was completely broken so its likely some mismatch between
your setup and what is in the particular mirror you're using.
