Introduce the 'debug-kernel' script to allow developers to quickly attach a debugger to the QEMU debug remote. The setting (-s) is already enabled by ./run today when using QEMU for virtualisation. If the system is running under QEMU, the debugger will break in when the script is run. If you add the -S option to QEMU it will wait for the debugger to connect before booting the kernel. This allows you to debug the init/boot process. Personally I use cgdb instead of gdb, so I opted to make the debugger used by the script customizable via an environment variable. This change also adds -g3 to the kernel build so that rich debug symbols are available in the kernel binary.
