Rainer Orth 281c444773 Remove support for Solaris < 10 (PR gdb/22185)
Given that GCC has obsoleted/removed support for Solaris 9 in GCC 4.9/5 in 2013:

    https://gcc.gnu.org/gcc-4.9/changes.html
    https://gcc.gnu.org/ml/gcc-patches/2013-05/msg00728.html

and the last gdb version that can be compiled with gcc 4.9 is 7.12.1 only when
configured with --disable-build-with-cxx, it's time to obsolete/remove support
for Solaris < 10.

This patch does this, simplifying configure.nat along the way (only a single
sol2 configuration with variants for i386 and sparc).

Some configure checks for older Solaris versions can go, too, and the check
for libthread_db.so.1 removed:

* Since Solaris 10, dlopen has moved to libc and libdl.so is just a
  filter on ld.so.1, so no need to check.

* $RDYNAMIC is already handled above (and is a no-op with Solaris ld
  anyway).

Both proc-service.c and sol-thread.c lose support for (Solaris-only)
PROC_SERVICE_IS_OLD.

The attached revised patch has been tested on sparcv9-sun-solaris2.10,
sparcv9-sun-solaris2.11.4, amd64-pc-solaris2.10, amd64-pc-solaris2.11.4,
and x86_64-pc-linux-gnu.

I've also started an i386-pc-solaris2.9 build to check that it really
stops as expected.

	<i[34567]86-*-solaris*>: Remove.
	<sparc-*-solaris2.[0-6], sparc-*-solaris2.[0-6].*>: Remove.

		   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.
