Back in the day gdbserver was treated as a subproject of GDB and
even was located in "gdb/gdbserver" and so to build gdbserver we had
to go into "gdb/gdbserver" and there run configure. That way full GDB
was out of the picture.
Now starting from GDB 10.1 where gdbserver was promoted to the top-level
we're supposed to run top-level's configure script for all the tools
provided by the unified binutils-gdb tree.
That said if we only want to build gdbserver (and that's what we
want since we build one tool at a build step) we have to be explicit:
----------------->8----------------
--enable-gdbserver --disable--gdb
----------------->8----------------
Ah, and so far we used to build full native GDB when only wanted gdbserver
if it was GDB v10.x ;)
Ironically full native/target GDB also enabled gdbserver by default so
we need to also disable it explicitly with "--disable-gdbserver".

Since we have curses built for target anyway now, why don't allow
users to use very convenient pseudo-GUI operating mode?
And while at it, there's no use of TUI in naturally headless gdbserver.

With this we may finally build Windows and "native" toolchains
if host tools are also GCC11 based. For example:
1. You build cross toolchain with all the recent components by CT-NG
2. You build cross-canadian toolchain for Windows or ARC, ARMm whatever board
See upstream bug report [1] for more details.
Basically when we do cross-canadian build with
use of the same GCC11 as a "host" compiler we're seeing
an error like that:
------------------->8-------------------
mingw-w64-cross/gcc/x86_64-w64-mingw32/libstdc++-v3/include/fenv.h:58:11: error: 'fenv_t' has not been declared in '::'

This is a solution proposed by Yujie Yang in [2]
Note, though it's not the final fix merged upstream, that's just
an attempt to fix this by casual GCC users. There's a hope it
will be fixed anyways a bit later, maybe by the time of GCC 11.3...

Here we add a couple of fixes and improvements for ARC processors.
All except 1 patch are already in the upstream "master" branch
and will be an essential part of GCC 11.x whenever it gets released.
The most important are first 4 patches (0005-0008) which introduce
support of full native GDB support in Linux on ARC.
And the rests are tiny, yet useful improvements.

"--with-host-libstdcxx" option was removed in GCC 6.x, see [1] because of [2].
So it makes no sense to use it with later GCC versions.
Frankly I don't like that implementation with yet another set of "if XXX",
but since we still support GCC down to 4.8.5 what else we may do?
Well, technically we may keep using things as they are now,
because surprisingly GCC's configure script doesn't mind accepting
meaningless options, but as a person who's looking at differences between
various builds and drill-down to peculiarities of various config
options, I'd prefer to not pollute configure with garbage.
But for all the rest... well, it works now and maybe nodody else cares.

GCC 11+ requires compiler being used to support C++11 standard [1].
And while GCC starting from 6.x has C++11 support enabled by default [2],
older versions need to be forced to implement it with "-std=gnu++11" and luckily
GCC's build-system takes care of that:
1. For ${host} compiler - [1]
2. For ${build} compiler - [3, 4]
In a nutshell the configure script tries a couple of options and the one which
helps to build a test source gets appended to CXX (not CXXFLAGS!),
so on say CentOS 7.x with GCC 4.8.5 during cross-compilation of GCC
CXX="x86_64-build_pc-linux-gnu-g++ -std=gnu++11". And all is good.
But in case of canadian cross due to [5] we for some reason* force set
CXX_FOR_BUILD with just a compiler name, effectively overriding all the
magic done by GCC's internals described above.
This leads to a compilation failures like that:

* my guess that [5] was done because back in the day indeed we used to have
"--build=${CT_BUILD} --host=${CT_HOST}" in do_cc_core(). But now after [6]
this is no longer necessary as we use "--build=${CT_BUILD} --host=${CT_BUILD}"
and all is safe and clean. So yet another old quirk goes away - hooray!

GCC can support using zstd compression for LTO object files. By default
GCC's configure will enable this if libzstd is installed on the machine
building the toolchain. This may be undesirable if the toolchain is to
be used on a different machine. Add an option to control zstd usage and
set the default to the same as the current behaviour (i.e. auto).

In GDB 10.x gdbserver was promoted to the top-level folder,
see https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=919adfe8409211c726c1d05b47ca59890ee648f1
Which means it is no longer a subfolder in "gdb" and so we have to
build gdbserver now exactly in the same way as normal native GDB.
One interesting detail is gdbserver doesn't need to deal with target
description in .xml so it doesn't depend on libexpat on target,
thus we need to move libexpat explicit selection from do_gdb_backend()
to its callers when building native [full] gdb as well as cross-gdb
for the host.

Older ARC700 processors had atomic instructions (AKA llock/scond)
as an option and so quite some "atomic" operations were not possible
w/o OS support, which we implemented - see arc_usr_cmpxchg() in the
Linux kernel.
And in uClibc, which was the only Linux libc back in the day of ARC700
era, it is well supported. Well, uClibc could be configured to support it.
Which is done with CONFIG_ARC_HAS_ATOMICS Kconfig option.
But the problem is there's no check for ARC ISA version in uClibc when
this option gets enabled. That leads to a funny situation when even for
ARCv2 processors (ARC HS3x & HS4x) uClibc tries to utilize
arc_usr_cmpxchg() syscall which is not supported for this newer ISA since
ARCv2 processors have atomic instructions built-in all the time.
So what was happening here we didn't specify additional "-matomic"
CFLAG unless we were targeting exactly those ancient ARC770 processors
(ARC700 + MMUv3 + atomics) and so even for ARCv2 we forced uClibc
to not use built-in atomics.
And even though there're ways to add a smarter solution here to handle
that pretty rare by now case of ARC750 (ARC700 + MMUv2 - atomics),
I suggest we just remove this part completely, leaving a possibility
to add needed option in uClibc-ng's configuration
(I mean "packages/uClibc-ng/config").
