Stafford Horne a76ef689b6 or1k: Fix issue with plt link failure for local calls
When building protobuf we were seeing the assert failure:

    /home/giuliobenetti/git/upstream/or1k-binutils-2.36.1/host/lib/gcc/or1k-buildroot-linux-uclibc/9.3.0/../../../../or1k-buildroot-linux-uclibc/bin/ld:
    BFD (GNU Binutils) 2.36.1 assertion fail elf32-or1k.c:2377
    /home/giuliobenetti/git/upstream/or1k-binutils-2.36.1/host/lib/gcc/or1k-buildroot-linux-uclibc/9.3.0/../../../../or1k-buildroot-linux-uclibc/bin/ld:
    BFD (GNU Binutils) 2.36.1 assertion fail elf32-or1k.c:2377
    /home/giuliobenetti/git/upstream/or1k-binutils-2.36.1/host/lib/gcc/or1k-buildroot-linux-uclibc/9.3.0/../../../../or1k-buildroot-linux-uclibc/bin/ld:
    BFD (GNU Binutils) 2.36.1 assertion fail elf32-or1k.c:2377
    collect2: error: ld returned 1 exit status

This failure happens while writing out PLT entries, there is a check
"BFD_ASSERT (h->dynindx != -1)" to confirm all plt entries have dynamic
symbol attributes.  This was failing for symbols that were
"forced_local" in previous linking code.

The fix adds logic to or1k_elf_adjust_dynamic_symbol to identify
"forced_local" symbols and exclude them from the the PLT.

bfd/ChangeLog:

	PR 27624
	* elf32-or1k.c (or1k_elf_adjust_dynamic_symbol): Change
	condition used to cleanup plt entries to cleanup forced local
	entries.

		   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.
