- If you say Y here, it will be possible to remotely debug the kernel
- using gdb. This enlarges your kernel ELF image disk size by several
- megabytes and requires a machine with more than 16 MB, better 32 MB
- RAM to avoid excessive linking time. This is only useful for kernel
- hackers. If unsure, say N.

- possible, leaving the program counter at the beginning of

- that GDB prints them as program output, say 'Y'.
