Luis Machado acdf60711d pauth: Create new feature string for pauth to prevent crashing older gdb's
Older gdb's (9, 10, 11 and 12) have a bug that causes them to crash whenever
a target reports the pauth feature string in the target description and also
provide additional register outside of gdb's known and expected feature
strings.

This was fixed in gdb 13 onwards, but that means we're stuck with gdb's out
there that will crash on connection to the above targets.

QEMU has postponed inclusion of the pauth feature string in version 8, and
instead we agreed to use a new feature name to prevent crashing those older
gdb's.

Initially there was a plan to backport a trivial fix all the way to gdb 9, but
given QEMU's choice, this is no longer needed.

This new feature string is org.gnu.gdb.aarch64.pauth_v2, and should be used
by all targets going forward, except native linux gdb and gdbserver, for
backwards compatibility with older gdb's/gdbserver's.

gdb/gdbserver will still emit the old feature string for Linux since it doesn't
report additional system registers and thus doesn't cause a crash of older
gdb's. We can revisit this in the future once the problematic gdb's are likely
no longer in use.

I've added some documentation to explain the situation.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
