This isn't the right approach.  First, thanks for figuring out the
slight rodata change that happens when testing some Kconfig rework
series.  However, this first violates the principal of least surprise as
you're turning off part of the build that was on before.  Second, it's
not the only zlib in the build, and it's often reproducible.

We should have a section somewhere in the docs about tips and tricks for
doing Kconfig rework as there's other things too such as not having the
baseline commit to compare with be a version tag since everything will
grow slightly due to then having a githash appending to it.
