     Change dwarf2_initialize_objfile's return value

     dwarf2_initialize_objfile was returning boolean whether it is psymtabs
     or .gdb_index while now it needs to return also whether it is
     .debug_names.
~~~~

breaks non-ELF-target builds:

 dwarf2read.o: In function `dwarf2_initialize_objfile(objfile*)':
 /home/yao.qi/SourceCode/gnu/binutils-gdb/gdb/dwarf2read.c:6486:
 undefined reference to `elf_sym_fns_gdb_index'
 /home/yao.qi/SourceCode/gnu/binutils-gdb/gdb/dwarf2read.c:6490:
 undefined reference to `elf_sym_fns_debug_names'
 /home/yao.qi/SourceCode/gnu/binutils-gdb/gdb/dwarf2read.c:6495:
 undefined reference to `elf_sym_fns_lazy_psyms'
 collect2: error: ld returned 1 exit status
	 Makefile:1920: recipe for target 'gdb' failed

because gdb/elfread.c is not included in the gdb build unless bfd also
includes elf support.

Fix this by reverting the patch mentioned above and at the same time
re-adding .debug_names support by adding a new output parameter to
dwarf2_initialize_objfile to indicate the index variant in use.  We
can reuse the new dw_index_kind enum in dwarf2read.c for that.

gdb/ChangeLog:
2017-12-11  Pedro Alves  <palves@redhat.com>

	* defs.h (elf_sym_fns_lazy_psyms, elf_sym_fns_gdb_index)
	(elf_sym_fns_debug_names): Move to elfread.c.
	* dwarf2read.c (dwarf2_initialize_objfile): Return a boolean
	instead of a sym_fns and add 'index_kind' output parameter.  Fill
	the latter in with the index variant kind if using an index.
	(enum dw_index_kind): Moved to symfile.h.
	* elfread.c (elf_sym_fns_gdb_index, elf_sym_fns_debug_names)
	(elf_sym_fns_lazy_psyms): Move from defs.h.
	(elf_symfile_read): Adjust to new dwarf2_initialize_objfile
	interface.
	* symfile.h (enum class dw_index_kind): New, moved from
	dwarf2read.c.
	(dwarf2_initialize_objfile): Change prototype.

		   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.
