configs/debug: set CONFIG_DEBUG_INFO=y properly

Qian Cai · torvalds · commit d1eff16d727f · 2022-03-05T11:08:33.000-08:00
CONFIG_DEBUG_INFO can't be set by user directly, so set CONFIG_DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT=y instead. Otherwise, we end up with no debuginfo in vmlinux which is a big no-no for kernel debugging.
