Yao Qi b1b53fb3ef Fix fail in gdb.server/solib-list.exp
If I run single test solib-list.exp, it is OK.  If I run two, as below,
there are fails,

$ make check RUNTESTFLAGS="server-run.exp solib-list.exp"
FAIL: gdb.server/solib-list.exp: non-stop 0: continue (the program exited)
FAIL: gdb.server/solib-list.exp: non-stop 0: p libvar
FAIL: gdb.server/solib-list.exp: non-stop 1: continue (the program exited)
FAIL: gdb.server/solib-list.exp: non-stop 1: p libvar

in gdb.log,

/scratch/yao/gdb/build-git/x86_64/gdb/testsuite/../../gdb/gdbserver/gdbserver --once :2347 /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/outputs/gdb.server/server-run/server-run /lib64/ld-linux-x86-64.so.2 /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/outputs/gdb.server/solib-list/solib-list

server-run is spawned, which is wrong.  If I only run solib-list.exp, ld-linux
is spawned, which is right.

/scratch/yao/gdb/build-git/x86_64/gdb/testsuite/../../gdb/gdbserver/gdbserver --once :2346 /lib64/ld-linux-x86-64.so.2 /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/outputs/gdb.server/solib-list/solib-list

in test, we spawn gdbserver this way,

    # Note we pass ${interp_system}, the program gdbserver spawns, as
    # argument here, instead of using gdb_load, because we don't want
    # to download the interpreter to the target (it's already there)
    # or to the test output directory.
    set res [gdbserver_spawn "${interp_system} ${remote_binfile}"]

in gdbserver_spawn -> gdbserver_download_current_prog, if
last_loaded_file is set (when you run multiple tests), it is
returned.

This patch is to unset last_loaded_file in solib-list.exp.

		   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.
