Commit Message

Andy Whitcroft March 1, 2024, 2:09 p.m. UTC
linux-buildinfo packages are now externally compared by swm, with
results approving or rejecting updates based on the stable
tracker. Those checks also allow hints and overrides to accept
intentional changes.

Also these are done on the correct pair-wise comparisons, especially
when two streams are being cranked.

The above eliminates the need to identify previous build abi,
download, extract it, vendor it in, and assert it at build time.
