Sorry, I'm not following: no matter how many debug registers the PPC
has, it can still return to GDB the data address that triggered the
watchpoint.  I don't think the higher levels of GDB (breakpoint.c)
should know or assume anything about the target capabilities or
resources.  Let's try keeping the code clean of such peculiarities.
