[yocto] Non-deterministic build error in package gcc-source

[Burton, Ross]

Obvious short answer is do you actually need to use the archiver in
patched mode?  Changing to a different mode, or disabling the archiver
entirely, may solve this.

Long answer is this is most likely a race in the archiver, so filing a
bug with as many details as you can would be good.
