Rainer Orth a5def729be Disable R_X86_64_PLT32 generation as branch marker on Solaris/x86
The fix H.J. implemented for PR gas/22791 in the thread starting at

	[PATCH] x86-64: Treat PC32 relocation with branch as PLT32
	https://sourceware.org/ml/binutils/2018-02/msg00065.html

is causing problems on Solaris/x86.  The native linker is strongly
preferred there, and there's no intention of implementing the linker
optimization he plans there.  Besides, the kernel runtime linker,
otherwise has no need to deal with that reloc at all, and instead of
adding (possibly even more) workarounds with no benefit, it seems
appropriate to disable the R_X86_64_PLT32 generation as branch marker on
Solaris/x86 in the first place.

The patch itself is trivial, the only complication is adapting the
testsuite.  Since I've found no way to have conditional sections in the
.d files, I've instead used the solution already found elsewhere of
having separate .d files for the affected tests in an i386/solaris
subdirectory and skipping the original ones.

Tested on amd64-pc-solaris2.11 and x86_64-pc-linux-gnu without
regressions.

		   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.
