After building the cross toolchain and compile a simple C program,
objdump reports debug information even though -g modifier was not
used. These debug segments are in glibc library and CRT files. So
a new config entry: CT_GLIBC_ENABLE_DEBUG was added to control when
we want to add debug information to glibc, by default is enabled.

When `CT_NEWLIB_NANO_INSTALL_IN_TARGET=y`, the `nano.specs` file
emitted by the newlib-nano build script contains an invalid include
path, resulting in the full `newlib.h` being included instead of the
nano `newlib.h` by the application.
`=/include/newlib-nano` is not a valid path (`=` does not mean anything
and that string is taken as an include path as-is) and GCC ignores this
include path, resulting in application including the `newlib.h` from
`include/` which contains the newlib build configurations for the full
newlib.
This commit modifies the newlib-nano build script to emit a proper
newlib-nano include path relative to the `GCC_EXEC_PREFIX`.

In Bryan Hundven's patch 1ad439907 from 2010, the author added -lstdc++
and -lm to the host gcc build's LDFLAGS, because at the time the linker
did not correctly include these libraries causing the build to fail.
In modern builds, this causes a problem for canadian gcc builds where
the host machine is mingw32-w64 Windows.
Within the gcc build there is the liblto_plugin module. On Windows this
must be built as the "liblto_plugin.dll" dynamic library. However,
libtool cannot produce a dynamic library unless every library dependency
is also a dynamic library, and falls back to producing a libstdc++.a
static library. liblto_plugin does not require libstdc++ - it
does not contain any C++ code, and the dependency would usually be
elided by the linker.
Unfortunately, in this case, crosstool-ng will never build a
libstdc++.dll dynamic library - only a libstdc++.a static library.
Therefore, there will never be a dynamic library version of stdc++ for
libtool to load and then discard.
This patch corrects the issue by removing "-lstdc++" from LDFLAGS,
because modern versions of gcc are able to correctly include libstdc++
where necessary. It also remove "-lm" for similar reasons.

After 557b9d4, libc_start_files and libc_main steps are performed one
after another. It doesn't make sense, especially since some of the libcs
(glibc, uClibc-ng) go to great lengths to first install start files in
the first step, libc_start_files, only to remove them immediately in the
second step, libc_main.
Current build steps also break in the xtensa newlib configurations, as
it needs to install the custom xtensa headers before building the libgcc
and after 557b9d4, the headers are not installed before libgcc is built
in pass-1.
Therefore, finish what 557b9d4 mentioned but did not do: move header
installation into a new step, libc_headers, and combine libc_start_files
and libc_main into a single step.
This also allows to combine the core pass-1/pass-2 steps, to be done in
a subsequent commit.

Per https://github.com/crosstool-ng/crosstool-ng/issues/808 build static
libgcc in the first pass which lets us skip the second one. Building
mingw-w64 requires header files in order to build C++ support so mingw
builds core pass 2. This could probably be cleaned up by splitting
libc_start_files into a separate libc_header step. But for now having
core 2 for mingw-w64 and core 1 for the other libcs will have to do.
Anything that previously selected CC_CORE_PASSES_NEEDED now selects
CC_CORE_PASS_1_NEEDED. The same goes for CC_CORE_PASS_2_NEEDED with the
exception of mingw-w64.

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".

"--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

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").
