That's because there's a LOT of noise in the merge_config log, the
separate task for doing the audit has heuristics to highlight
important errors, and allows configuration fragments to override each
other, have optional fragments, etc.
I already have the various audit level variables in use for
linux-yocto style kernels, at the highest level it could be dumped,
but absolutely not by default.
