[rfc] Define PTRACE_GETSIGINFO in linux-nat.c

[Markus Deuling <deuling@de.ibm.com>]

Hi,

the new save_siginfo() function from linux-nat.c breaks my build on

  Linux bbkeks 2.6.9-55.0.6.EL #1 Thu Aug 23 10:59:21 EDT 2007 i686 i686 i386 GNU/Linux

because PTRACE_GETSIGINFO isn't defined in the includes. The patch takes over definition of it from ppc-linux-nat.c


ChangeLog:

	* linux-nat.c (PTRACE_GETSIGINFO): Add define.

Tested on x86.

Is this ok to commit or would it be better to move it to a header (linux-nat.h ?) file and delete it from ppc-linux-nat.c as well to prevent 
redundancy?

Regards,
Markus
