Import the strerror_r-posix module and use it in GDB.

Browse Source 
Makes sure to assign the return value of strerror_r to an int,
so that we get a compile error if we accidentally get the
wrong version.

gdb/ChangeLog:

2019-11-15  Christian Biesinger  <cbiesinger@google.com>

	* config.in: Regenerate.

	* gdbsupport/posix-strerror.c (safe_strerror): Always call the
	POSIX version of strerror_r, now that gnulib provides it if
	necessary.

# This file is free software; the Free Software Foundation gives

# The first argument passed to this file is the canonical host specification,
# CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
# or
# CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
# The environment variables CC, GCC, LDFLAGS, LD, with_gnu_ld
# should be set by the caller.
#
# The set of defined variables is at the end of this script.
# Known limitations:
# - On IRIX 6.5 with CC="cc", the run time search patch must not be longer
# than 256 bytes, otherwise the compiler driver will dump core. The only
# known workaround is to choose shorter directory names for the build
# directory and/or the installation directory.
# All known linkers require a '.a' archive for static linking (except MSVC,
# which needs '.lib').

dnl gl_THREADLIB
dnl ------------
dnl Tests for a multithreading library to be used.
dnl If the configure.ac contains a definition of the gl_THREADLIB_DEFAULT_NO
dnl (it must be placed before the invocation of gl_THREADLIB_EARLY!), then the
dnl default is 'no', otherwise it is system dependent. In both cases, the user
dnl can change the choice through the options --enable-threads=choice or
dnl --disable-threads.
dnl Defines at most one of the macros USE_POSIX_THREADS, USE_SOLARIS_THREADS,
dnl USE_PTH_THREADS, USE_WINDOWS_THREADS
dnl Sets the variables LIBTHREAD and LTLIBTHREAD to the linker options for use
dnl in a Makefile (LIBTHREAD for use without libtool, LTLIBTHREAD for use with
dnl libtool).
dnl Sets the variables LIBMULTITHREAD and LTLIBMULTITHREAD similarly, for
dnl programs that really need multithread functionality. The difference
dnl between LIBTHREAD and LIBMULTITHREAD is that on platforms supporting weak
dnl symbols, typically LIBTHREAD is empty whereas LIBMULTITHREAD is not.
dnl Adds to CPPFLAGS the flag -D_REENTRANT or -D_THREAD_SAFE if needed for
dnl multithread-safe programs.
