CONFIG_KALLSYMS_ALL and CONFIG_DEBUG_FS are rather fundamental, and
are enabled in most other architectures as well. I would recommend
everything that is needed to run on the most common hardware
configurations and that is needed for booting into a general-purpose
distribution, but not much beyond that.

Other options like CONFIG_DEBUG_INFO and CONFIG_DEBUG_KERNEL (including
options based on it) are probably better left disabled though, those
are the ones with a significant runtime or buld-time overhead.
