So, MODVERSIONS was off, but MODULE_SRCVERSIONS_ALL and
LOCALVERSION_AUTO were on.

Repeating with those turned off, nothing was rebuilt.

That was bootable, too.  So I turned them on individually
and each was still bootable.  I verified the config matched
the originals I started with.

So I cleaned my tree and started over building v4.3.5 then v4.4.1.
They both booted.  So I can no longer reproduce this.

Sorry for the noise.
