Merge configure.ac from gcc project

Browse Source 
To merge with gcc's copy of configure.ac we need to revert changes to
configure.ac in the following gcc commits:
dc832fb39fc0 2022-08-25
fc259b522c0f 2022-06-25
Then reapply configure.ac changes in binutils from these binutils
commits:
50ad1254d503 2021-01-09
bb368aad297f 2022-03-11
e5f2f7d901ee 2022-07-26
2cac01e3ffff 2022-09-26
Plus copy over gcc's config/ax_cxx_compile_stdcxx.m4, then regenerate
configure.

#
# SYNOPSIS
#
# AX_CXX_COMPILE_STDCXX(VERSION, [ext|noext], [mandatory|optional])
#
# DESCRIPTION
#
# Check for baseline language coverage in the compiler for the specified
# version of the C++ standard. If necessary, add switches to CXX and
# CXXCPP to enable support. VERSION may be '11' (for the C++11 standard)
# or '14' (for the C++14 standard).
#
# The second argument, if specified, indicates whether you insist on an
# extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
# -std=c++11). If neither is specified, you get whatever works, with
# preference for no added switch, and then for an extended mode.
#
# The third argument, if specified 'mandatory' or if left unspecified,
# indicates that baseline support for the specified C++ standard is
# required and that the macro should error out if no mode with that
# support is found. If specified 'optional', then configuration proceeds
# regardless, after defining HAVE_CXX${VERSION} if and only if a
# supporting mode is found.
#
# If the fourth argument is an optional CXX/CXXFLAG/CPPFLAG suffix, e.g.
# "_FOR_BUILD" or "_FOR_TARGET".
