Second Resolute Raccoon test rebuild

[Graham Inggs]

The second test rebuild of Resolute Raccoon was started on March 20,
2026 for all architectures and all components. The rebuild is finished
for the main component on all architectures except riscv64, and still
running for universe and multiverse.

Results (please also look at the superseded builds) can be found at:

Additional build failures for packages in resolute-proposed (not yet
in Resolute) can be found at:

http://qa.ubuntuwire.com/ftbfs/

Please help with fixing the build failures.

There is also a test rebuild with GCC 16 as default.  Resolute will
ship with GCC 15 as the default and GCC 16 as an optional compiler.

Happy equinox!
