Subject: [PATCH 1/1] gdb: Fix ia64 defining TRAP_HWBKPT before including
 gdb_wait.h

On ia64, gdb_wait.h eventually includes siginfo-consts-arch.h, which
contains an enum with TRAP_HWBKPT, along with a #define. Thus we cannot
define TRAP_HWBKPT to 4 beforehand, and so gdb_wait.h must be included
earlier; include it from linux-ptrace.h so it can never come afterwards.
