Sandra Loosemore 25dfed247b Fix more bugs in gdb testglue wrapper handling
In commit 24ac169ac5, this patch:

	2020-02-21  Shahab Vahedi  <shahab@synopsys.com>

	* lib/gdb.exp (gdb_wrapper_init): Reset
	"gdb_wrapper_initialized" to 0 if "wrapper_file" does
	not exist.

attempted to fix problems finding the gdb test wrapper gdb_tg.o in
some tests that cd to some non-default directory by rebuilding also
the test wrapper in that directory.  This had the side-effect of
leaving these .o files in various places in the GDB source directory
tree.

Furthermore, while the tests that cd to some non-default directory
cannot run on remote host, the code that was added to probe for the
presence of the wrapper file was also specific to host == build.

This patch reverts the problematic parts of that commit and replaces
it with forcing use of an absolute (rather than relative) pathname to
the .o file for linking when host == build.

While debugging this patch, I also observed that use of the construct
"[info exists gdb_wrapper_file]" was not reliable for detecting when
that variable had been initialized by gdb_wrapper_init.  I rewrote
that so that the variable is always initialized and has a value of an
empty string when no wrapper file is needed.

	gdb/testsuite/
	* lib/gdb.exp (gdb_wrapper_file, gdb_wrapper_flags):
	Initialize to empty string at top level.
	(gdb_wrapper_init): Revert check for file existence on build.
	Build the wrapper in its default place, not a build-specific
	location.  When host == build, make the pathname absolute.
	(gdb_compile): Delete leftover declaration of
	gdb_wrapper_initialized.  Check gdb_wrapper_file being an empty
	string instead of uninitialized.

		   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.
