I had a feeling that was the expectation. Just for reference, my flow
for generating fragments looks like the following.

  1. make allnoconfig
  2. make menuconfig   # select the options that I desire for the fragment

We can drop this patch if this is the expected developer flow. I
realized that overriding with 'is not set' entries in a fragment is
likely desirable, so I made this behavior change as part of a flag that
can be set by the user.
