Alan Modra 1e3b96fd6c Allow plugin syms to mark as-needed shared libs needed
We must tell LTO about symbols in all shared libraries loaded.  That
means we can't load extra shared libraries after LTO recompilation, at
least, not those that affect the set of symbols that LTO cares about,
the IR symbols.

This change will likely result in complaints about --as-needed
libraries being loaded unnecessarily, but being correct is more
important than being optimal.  One of the PR15146 tests regresses, and
while that could be hidden by disabling the missing dso message by
making it conditional on h->root.non_ir_ref_regular, that would just
be sweeping a problem under the rug.

	PR 15146
	PR 26314
	PR 26530
	* elflink.c (elf_link_add_object_symbols): Do set def_regular
	and ref_regular for IR symbols.  Don't clear dynsym, allowing
	IR symbols to load --as-needed shared libraries, but prevent
	IR symbols from becoming dynamic.

		   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.
