We do have very rudimentary gdb serial debug support in the kernel, so
attaching a gdb via serial connection works in principle, but stepping,
breakpoints, and other stuff doesn't work yet. Besides, when I last tested it,
gdb (under Linux) hung trying to load a gcc 2 Haiku kernel, which kind of
spoiled my motivation to extend the support. Later I found out that the gcc 4
kernel is loaded fine, though, so it might be worthwhile to pursue that
eventually.
