That's a reason to not use --target noarch, e.g. the above would work
in reproducing a kernel sources tree actually used by Red Hat (he will
not see a difference in the diff like you do).

If you use --target noarch you get config files that are _recommended_
by Red Hat as a basis for creating custom kernels. There the
CONFIG_DEBUG switches have been changed. If you use --target no-noarch
;) then the config files remain untouched.

so it depends on what you need the kernel sources for, creating kernel
modules for Red Hat shipped kernels (the don't use noarch), or
creating your own kernels (use noarch).
