v3 changes:
Use correct automake macro for target cpu
There's been a lot of changes since v1. There are more fixes and more
features. The majority of the shell code has been moved to an external
file named gdb_helper.sh, instead of being inline in the GDB script. The
one (direct) PERL dependency in GRUB has been removed and converted to
shell script. Also a section on debugging is added to the developer docs.
