Same idea as my never-download-microcode patch. Even if a
coreboot config enables blobs, the blobs are not actually
downloaded or inserted or otherwise handled in any way.
This means I can re-use lbmk-based coreboot configs without
as much modification, thus reducing the maintenance burden
for Canoeboot releases.
