Pedro Alves 451953fa44 Eliminate the 'the_core_target' global
(previously called 'core_target', but since renamed because
'core_target' is the name of the target_ops class now.)

This eliminates the "the_core_target" global, as preparation for being
able to have more than one core loaded.  When we get there, we will
instantiate one core_target object per core instead.

Essentially, this replaces the reference to the_core_target in
core_file_command by a reference to core_bfd, which is per
program_space.

Currently, core_file_command calls 'the_core_target->detach()' even if
the core target is not open and pushed on the target stack.  If it is
indeed not open, then the practical effect is that
core_target::detach() prints "No core file now.".  That is preserved
by printing that directly from within core_file_command if not
debugging a core.

gdb/ChangeLog:
2018-05-11  Pedro Alves  <palves@redhat.com>

	* corefile.c (core_file_command): Move to corelow.c.
	* corelow.c (the_core_target): Delete.
	(core_file_command): Moved from corefile.c.  Check exec_bfd
	instead of the_core_target.  Use target_detach instead of calling
	into the_core_target directly.
	(maybe_say_no_core_file_now): New.
	(core_target::detach): Use it.
	(_initialize_corelow): Remove references to the_core_target.
	* gdbcore.h (the_core_target): Delete.

		   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.
