Tom de Vries a561456f2d [gdb/testsuite] Fix gdb.arch/i386-pkru.exp on linux
When running test-case gdb.arch/i386-pkru.exp on a machine with "Memory
Protection Keys for Userspace" support, we run into:
...
(gdb) PASS: gdb.arch/i386-pkru.exp: probe PKRU support
print $pkru^M
$2 = 1431655764^M
(gdb) FAIL: gdb.arch/i386-pkru.exp: pkru register
...

The test-case expects the $pkru register to have the default value 0, matching
the "init state" of 0 defined by the XSAVE hardware.

Since linux kernel version v4.9 containing commit acd547b29880 ("x86/pkeys:
Default to a restrictive init PKRU"), the register is set to 0x55555554 by
default (which matches the printed decimal value above).

Fix the FAIL by accepting this value for linux.

Tested on x86_64-linux.

		   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.
