H.J. Lu e133d00576 i386: Avoid dynamic symbol with GOT reference in PIE
GOT reference to global symbol in PIE will lead to dynamic symbol.  It
becomes a problem when "time" or "times" is defined as a variable in
an executable, clashing with functions of the same name in libc.  If
a symbol isn't undefined weak symbol, don't make it dynamic in PIE and
generate R_386_RELATIVE relocation.

bfd/

	PR ld/21402
	* elf32-i386.c (elf_i386_link_hash_entry): Add
	no_finish_dynamic_symbol.
	(elf_i386_link_hash_newfunc): Set no_finish_dynamic_symbol to 0.
	(elf_i386_allocate_dynrelocs): If a symbol isn't undefined weak
	symbol, don't make it dynamic in PIE.
	(elf_i386_relocate_section): If a symbol isn't dynamic in PIE,
	set no_finish_dynamic_symbol and generate R_386_RELATIVE
	relocation for R_386_GOT32
	(elf_i386_finish_dynamic_symbol): Abort if no_finish_dynamic_symbol
	isn't 0.

ld/

	PR ld/21402
	* testsuite/ld-elf/indirect.exp: Don't skip PIE indirect5 and
	indirect6 tests on i386.

		   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.
