kconfig.debug: clarify CONFIG_DEBUG_INFO help text
The following patch adds some extra clarification to the CONFIG_DEBUG_INFO
Kconfig help text. The current text is mostly a recursive definition and
doesn't really say much of anything. When I first read this I thought it
was going to enable extra verbosity in debug messages or something, but it
is only enabling the "gcc -g" compile option in the Makefile.

help
If you say Y here the resulting kernel image will include
debugging info resulting in a larger kernel image.
+ 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 unsure, say N.
