Tom de Vries a08bdb159b [gdb/build] Fix gdbserver build with -fsanitize=thread
[ Copied from gcc commit 153689603fd ("[gdb/build] Fix gdbserver build with
-fsanitize=thread"). ]

When building gdbserver with -fsanitize=thread (added to CFLAGS/CXXFLAGS) we
run into:
...
ld: ../libiberty/libiberty.a(safe-ctype.o): warning: relocation against \
  `__tsan_init' in read-only section `.text'
ld: ../libiberty/libiberty.a(safe-ctype.o): relocation R_X86_64_PC32 \
  against symbol `__tsan_init' can not be used when making a shared object; \
  recompile with -fPIC
ld: final link failed: bad value
collect2: error: ld returned 1 exit status
make[1]: *** [libinproctrace.so] Error 1
...
which looks similar to what is described in commit 78e4948694 ("[gdb/build]
Fix gdbserver build with -fsanitize=address").

The gdbserver component builds a shared library libinproctrace.so, which uses
libiberty and therefore requires the pic variant.  The gdbserver Makefile is
setup to use this variant, if available, but it's not there.

Fix this by listing gdbserver in the toplevel configure alongside libcc1, as a
component that needs the libiberty pic variant, setting:
...
extra_host_libiberty_configure_flags=--enable-shared
...

Tested on x86_64-linux.

ChangeLog:

2022-06-27  Tom de Vries  <tdevries@suse.de>

	* configure.ac: Build libiberty pic variant for gdbserver.
	* configure: Regenerate.

		   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.
