Tom de Vries c47860a4ba [gdb/testsuite] Fix stepi test-cases with unix/-m32/-fPIE/-pie
When running test-case gdb.base/step-indirect-call-thunk.exp with target board
unix/-m32/-fPIE/-pie, I run into:
...
(gdb) stepi^M
0x5655552e      22      {                /* inc.1 */^M
(gdb) stepi^M
0x56555530      22      {                /* inc.1 */^M
(gdb) stepi^M
0x565555f7 in __x86.get_pc_thunk.ax ()^M
(gdb) FAIL: gdb.base/step-indirect-call-thunk.exp: stepi into return thunk
...

In contrast, with unix/-m32 we have instead:
...
(gdb) stepi^M
0x08048407      22      {                /* inc.1 */^M
(gdb) stepi^M
23        return x + 1;  /* inc.2 */^M
(gdb) stepi^M
0x0804840c      23        return x + 1;  /* inc.2 */^M
(gdb) stepi^M
24      }                /* inc.3 */^M
(gdb) stepi^M
0x08048410      24      }                /* inc.3 */^M
(gdb) stepi^M
0x0804848f in __x86_return_thunk ()^M
(gdb) PASS: gdb.base/step-indirect-call-thunk.exp: stepi into return thunk
...

The test-case doesn't expect to run into __x86.get_pc_thunk.ax, which is a
PIC helper function for x86_64-linux.

Fix this by insn-stepping through it.

Likewise in a few other test-cases.

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

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