Can't talk to Angel debug monitor from arm-elf-gdb

[Dave Cleal]

Last time I'm going to do this. Just in case anyone else ever needs
to know, this now all works. The trick is to patch CDT (the Eclipse
plugin for C/C++ development) to recognise when you're connected via a
serial port, and to have it start the program with a "continue"
command not a "run" command. Everything thereafter works.
