These days old v5 ABI is not that relevant as it used to be back in
2015 when ncurses 6.x was added to CT-NG.
And now we see say target "gdb" relying on "libncurses.so.5",
while up-to-date Buildroot provides "libncurses.so" & "libncurses.so.6":
--------------------------->8-------------------------
$ ldd /bin/gdb
libncurses.so.5 => not found
libstdc++.so.6 => /lib/libstdc++.so.6 (0x20022000)
libm.so.6 => /lib/libm.so.6 (0x2017c000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x201ba000)
libc.so.6 => /lib/libc.so.6 (0x201c8000)
/lib/ld-linux-arc.so.2 (0x20000000)
--------------------------->8-------------------------
Switching to a default (v6 ABI) by default. And...
--------------------------->8-------------------------

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.

Issue #1535
GCC 10 changed the default to -fno-common, which leads to a linking error in GLibc older than 2.30.
This change adds -fcommon cflag for the target GLibc versions <=2.29 and GCC >=10.
This change also adds additional cflags for the target GLibc to disable
new GCC11 checks that lead to compilation errors.

Explicitly passing --disable-tm-clone-registry causes gcc to create a
crtbegin.o with a zero-sized .init_array/.fini_array. This in turn
causes ld to complain.
Make CC_GCC_TM_CLONE_REGISTRY a tristate so if it's not explicitly
enabled we can let ./configure decide.

This commit adds a new config that can be used to specify the target

By default, this config is set to specify the `-fno-exceptions` option,

GCC11 somehow has different set of multilibs on SH arch than what GCC10 had.
In particular:
$ gcc10 -print-multi-lib | sed -r -e 's/@/ -/g;'
.;
mb; -mb
m2; -m2
m2e; -m2e
m4; -m4
m4-single; -m4-single
m4-single-only; -m4-single-only
mb/m2; -mb -m2
mb/m2e; -mb -m2e
mb/m4; -mb -m4
mb/m4-single; -mb -m4-single
mb/m4-single-only; -mb -m4-single-only
mb/m2a; -mb -m2a
mb/m2a-single; -mb -m2a-single
$ gcc11 -print-multi-lib | sed -r -e 's/@/ -/g;'
.;
mb; -mb
m2; -m2
m2e; -m2e
m4; -m4
m4-single; -m4-single
m4-single-only; -m4-single-only
mb/m1; -mb -m1
mb/m2; -mb -m2
mb/m2e; -mb -m2e
mb/m4; -mb -m4
mb/m4-single; -mb -m4-single
mb/m4-single-only; -mb -m4-single-only
mb/m2a; -mb -m2a
mb/m2a-single; -mb -m2a-single
mb/m1 fails to build libgcc as libgcc uses opcodes that were not
available in SH-1: libgcc/config/sh/lib1funcs.S uses 'bt/s' and 'dt'
instructions that, according to https://antime.kapsi.fi/sega/files/h12p0.pdf become available in the SH-2 only.
So I removed mb/m1 from the multilibs fog GCC11 and SH arch.
Another option would be to try not to build libgcc for this combination
of the gcc version and archichecture, but I thought this fix would be
more robust.
