Pedro Alves 4043f22ba5 Get rid of "No such file or directory" in the testsuite's btrace support detection.
When I tried running the btrace tests, I noticed something odd in the gdb.log file:

 (gdb) run
 Starting program: /home/pedro/gdb/mygit/build/gdb/testsuite/gdb.btrace/btrace22343.x
 Breakpoint 1, main () at /home/pedro/gdb/mygit/build/gdb/testsuite/gdb.btrace/btrace22343.c:1
 1       /home/pedro/gdb/mygit/build/gdb/testsuite/gdb.btrace/btrace22343.c: No such file or directory.
                                                                             ^^^^^^^^^^^^^^^^^^^^^^^^^
 (gdb) record btrace
 Target does not support branch tracing.
 (gdb) testcase ../../../src/gdb/testsuite/gdb.btrace/enable.exp completed in 0 seconds

I knew that the btrace tests on my machine weren't supposed to work,
but still, that error made me wonder if the test had something broken,
and waste a few minutes looking up where that is coming from.

The issue is that the btrace detection deletes the source file right
after compiling it, and before GDB has a chance to open it.  It's
really harmless, but I'd rather spare others from going through the
same exercise.

We now get the regular:

 (gdb) run
 Starting program: /home/pedro/gdb/mygit/build/gdb/testsuite/gdb.btrace/btrace24210.x
 ...
 Breakpoint 1, main () at /home/pedro/gdb/mygit/build/gdb/testsuite/gdb.btrace/btrace24210.c:1
 1       int main(void) { return 0; }
 ...

		   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.
