Alan Modra 034fed0bbc ARC naughtiness causing assertion fail at elf-strtab.c:302
This patch fixes a number of issues in the ARC backend.

- The ARC size_dynamic_sections was trashing dynamic section contents,
  in particular the .gnu.version_d contents.  Those versions
  definitions are therefore lost so they do not drain from the strtab,
  resulting in assertion failures.
- The code attempting to set DT_TEXTREL was completely bogus.
- The ARC finish_dynamic_sections would segfault on trying to set
  sh_entsize for .rela.plt if that section had been discarded.
- arc_create_dynamic_sections wouldn't have ever created dynamics
  sections, which was just as well since the places it was called were
  way too late to create dynamic sections.  Its usefulness then
  devolved down to finding just one dynamic section.  All the others
  packaged into a struct were unused.
- .interp wasn't set for PIEs.

	* elf32-arc.c (struct dynamic_sections): Delete.
	(enum dyn_section_types): Delete.
	(dyn_section_names): Delete.
	(arc_create_dynamic_sections): Delete.
	(elf_arc_finish_dynamic_sections): Don't call the above.  Don't
	segfault on discarded .rela.plt section.
	(elf_arc_size_dynamic_sections): Formatting.  Don't call
	arc_create_dynamic_sections.  Don't allocate memory for sections
	handled by the generic linker.  Correct code finding relocs in
	read-only sections.  Set SEC_EXCLUDE on zero size .got,
	.got.plt, and .dynbss sections.  Do set .interp for pies.

		   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.
