Description Mathieu Dubois-Briand 2025-11-27 08:51:57 UTC 
Not sure if this is specific to the autobuilder configuration or something more broad:

AssertionError: Command 'bitbake  -e' returned non-zero exit status 1:
...
ERROR: A builtin fragment 'machine/qemux86-64' is used while MACHINE has already got an assignment.
Please either disable the fragment or remove the value assignment.
To disable the fragment, use 'bitbake-config-build disable-fragment machine/qemux86-64'.
