H.J. Lu f638657759 x86: Disallow invalid relocations against protected symbols
Since glibc 2.36 will issue warnings for copy relocation against
protected symbols and non-canonical reference to canonical protected
functions, change the linker to always disallow such relocations.

bfd/

	* elf32-i386.c (elf_i386_scan_relocs): Remove check for
	elf_has_indirect_extern_access.
	* elf64-x86-64.c (elf_x86_64_scan_relocs): Likewise.
	(elf_x86_64_relocate_section): Remove check for
	elf_has_no_copy_on_protected.
	* elfxx-x86.c (elf_x86_allocate_dynrelocs): Check for building
	executable instead of elf_has_no_copy_on_protected.
	(_bfd_x86_elf_adjust_dynamic_symbol): Disallow copy relocation
	against non-copyable protected symbol.
	* elfxx-x86.h (SYMBOL_NO_COPYRELOC): Remove check for
	elf_has_no_copy_on_protected.

ld/

	* testsuite/ld-i386/i386.exp: Expect linker error for PR ld/17709
	test.

		   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.
