With libc_headers step before pass-1, there is no need to distinguish
pass-1 and pass-2; they are configured identically (note that with the
current configuration, core pass-2 is only used for win32 - hence, uses
build_libgcc=yes and mode=static).

... and the code dependent on them, after the latest wave of obsolete
package removals. This concludes the glorious history of the original
uClibc (non-NG) with lots of kludges removed.
There was a choice here, whether to call the resulting libc "uClibc" or
"uClibc-ng". I opted in favor of giving uClibc-ng the recognition it
deserves, although it had some ripple effect in the ct-ng code.

The following versions were marked obsolete in crosstool-ng-1.24.0,
remove them.
- binutils-linaro-2.23.2-2013.10-4

- binutils-linaro-2.25.0-2015.01-2
- binutils-2.23.2
- binutils-2.24
- binutils-2.25.1
Adjust the milestones now that the old versions have been removed.

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).

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 gcc config `CT_CC_GCC_TM_CLONE_REGISTRY` that
enables the GCC transactional memory clone registry feature for libgcc.
Note that the gcc option to control this feature is only available in
gcc 10 and above.

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.

This has gone unnoticed for a while, it looks like all configurations
have probably been using the default floats behaviour. Newer kconfig
tells us the default value is not in the choice so lets fix this in

Also:
- Move companion_* to comp_* to match the kconfig symbols
- Replace bootstrap with former gen-versions.sh
- Fold *.in.2 into their respective first parts; this moves common
options to the end - if it is undesirable, inclusion of *.in
can be moved where *.in.2 used to be (but that will also move
version selection after common options).
- Retire addToolVersion.sh (may later replace with a more
comprehensive script that tries to download the added tarballs,
copy the patches and try to apply them, and create a version.desc).

Make this behavior default in case the core gcc backend is used
for final compiler (i.e., for baremetal configurations). Not
setting this option breaks canadian baremetal configurations,
and not setting it makes little sense at all in any baremetal
configuration (since in baremetal we don't have any libc to begin
with).
