How does GDB know if the target is local or remote?  Can the Linux
implementation of I386_DR_LOW_* macros test that and avoid calling
ptrace in that case?

Also, since I see that the Linux port of GDB was linking in
i386v-nat.c, and i386v-nat.c defined those same watchpoint-related
functions which called ptrace, and did that unconditionally, how did
that work before the last changes?
