patch for aix 4.3.3.07 support

[Geoff Keating <geoffk@geoffk.org>]

One of the changes in the 4.3.3.07 AIX maintenance release was
this code added to sys/ptrace.h:

/*
 * Linux compatibility section.
 * Define the Linux __ptrace_request enum.  This is not
 * ifdef'd because the library wrapper needs to see the enum
 * without the _LINUX_SOURCE_COMPAT redefines of the PT_* values.
 */
enum __ptrace_request {
	PTRACE_TRACEME,
	PTRACE_PEEKTEXT,
	PTRACE_PEEKDATA,
	PTRACE_PEEKUSER,
	PTRACE_POKETEXT,
	PTRACE_POKEDATA,
	PTRACE_POKEUSER,
	PTRACE_CONT,
	PTRACE_KILL,
	PTRACE_SINGLESTEP,
	PTRACE_GETREGS,
	PTRACE_SETREGS,
	PTRACE_GETFPREGS,
	PTRACE_SETFPREGS,
	PTRACE_ATTACH,
	PTRACE_DETACH,
	PTRACE_SYSCALL
};

Of course, these are not the same values as PT_ATTACH and PT_DETACH
(which are 30 and 31 respectively), and these values are not valid
unless you use __linux_ptrace() (which is #defined to be ptrace() if
you supply the right -D flag, which we don't want to do).  Happily,
gdb doesn't actually use PTRACE_ATTACH or PTRACE_DETACH anywhere, so
the only immediate problem is the #define.

Tested on powerpc-aix4.3.3; the attach.exp test passed.  OK to commit?
