hmm, I have an embedded target and I connect to it via a JTAG box, so
the target has hardware breakpoints, I assume we need to define them in
avr-tdep.c and put the hooks in the correct place to tie it together? 

What I see at the moment is the breakpoint.c stuff has no connection to
the avr-tdep.c file and I cannot see how to define something in avr-tdep
and let breakpoint.c use it.

Do you have some ideas about how this is supposed to work?
