Much like the kernel we try and pick sensible defaults.  In this case
you'd be removing a line from the defconfig files.

But you're not the first to suggest that something better could be done
here and maybe further down the line we'll play with the upstream tools
for merging defconfig snippets so that we could have some common ones
pulled together.
