Basically this means that these tasks tried to execute where really the 
results should have been able to be restored from sstate. 

The cause of this type of error is one of three things: 

1) The sstate archive corresponding to a task wasn't able to be fetched from 
the server (for a minimal eSDK) or wasn't present in the installer (for a full 
eSDK - less likely as we basically do a trial run as part of building the eSDK 
in the first place)

2) The signature was somehow different to what it should have been. (Locked 
signatures are supposed to guard against this.)

3) A task that wasn't expected to execute did execute and thus the sstate 
wasn't available.

Given that this was python-native which I would expect would be a normal part 
of the SDK, I would suspect #1. Is this a minimal or full eSDK (i.e. what is 
SDK_EXT_TYPE set to)?

Cheers,
Paul
