This adds debug symbols to the kernel and modules (gcc -g), and
is needed if you intend to use kernel crashdump or binary object
tools like crash, kgdb, LKCD, gdb, etc on the kernel.
- Say Y here only if you plan to debug the kernel.

+ If you only want to have resolved symbols in kernel traces and
+ are not going to need support for those tools above, you don't need
+ to enable this as it is a huge bloat and build slowdown;
+ enable CONFIG_KALLSYMS instead.
If unsure, say N.
