Python is listed as an optional dependency, but this is not true, as: 1) CONFIG_LTO_CLANG runs a python script at scripts/Makefile.vmlinux_o; 2) kernel-doc is called during compilation when some DRM options like CONFIG_DRM_I915_WERROR are enabled; 3) allyesconfig/allmodconfig will enable both. So, better document that.
