It doesn't work for me yet, but I don't see why not. It does work when I do
e.g. a 'make defconfig' in the current directory, but not when I set

It's probably easiest if you try to debug it yourself. It's as simple as:
$ mkdir /tmp/kbuild
$ KBUILD_OUTPUT=/tmp/kbuild make defconfig

One other thing. I wonder if this implementation will always reliably
result in the *current* SHA1 being included in the .config. AFAICT
the .config only actually gets written if there are changes, or if you
explicitly do a 'make oldconfig'.

But if you e.g. pull a stable update and just run 'make', the .config will
likely remain unchanged and will thus still contain the SHA1 from a
previous build.
