Allows building the #mold linker, which can then be used in the
cross-toolchain by passing the -fuse-ld=mold to the gcc flags. It is
much faster than ld or gold.
This requires a C++20 compiler and cmake.
Initially implemented by Arnaud, and HC added configure check for cmake.
Outstanding task to validate compiler is C++20 compatible.

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).

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.

Run samples through upgrade and fix accumulated breakages:
*-centos6-*: After 2.12.2 retirement, the samples selected most recent
glibc (2.34) which also forced kernels 3.2+. Revert to 2.12.1 and
2.6.32.71, respectively. Interestingly, 2.12.1 was marked as being used
in CentOS6, but the samples selected 2.12.2. Anyway, CentOS6 is EOL now
and glibc 2.12 is going to be marked obsolete, and retired soon.
arc-*: Make TARGET_VENDOR match the sample's name; otherwise `ct-ng
saveconfig` places the config file into a different location.
Fix 'savedefconfig' which was not saving the configuration file version
(CT_VCHECK was set to 'load' after CT_LoadConfig call).

This required some rework of the libc selection, as moxiebox is a layer on
top of another libc - newlib.
Also, moxiebox'es host VM (`sandbox`) needs a libcrypto on the host. We will
not have it if we're cross-compiling a canadian cross. Fortunately, all moxiebox
needs from libcrypto is SHA256, and it already includes a standalone implementation
of SHA256 in its runtime. Provide a little wrapper that allows moxiebox use
that implementation for the host binary, too.
Also, automate collecting/printing the list of all packages in a given category
(e.g. LIBC or COMP_TOOLS), generate a list of all Kconfig symbols for a given
category.

... for ct-ng configured without --enable-local. Also, install
licenses in subdirectories of the components.
Also, ct-ng configured with --enable-local removed the scripts directory

Also, misspelled CT_WGET/CT_CURL variables prevented use of

Automake does not allow us to place the hooks before its generated actions,
and does not allow us to check MAKECMDGOALS, and does not support a mechanism
for disabling make install (such as noinst_SUBDIRS, requested a few times
on automake mailing list). The only way I could preserve the current behavior
is to have a GNUmakefile wrapper that will convert MAKECMDGOAL into a variable
unknown to automake - which seems too convoluted a solution for the problem
being solved.
Hence the approach is to not override anything for --enable-local. It is now
fully handled by selecting different values for CT_xxx_DIR in ct-ng.in; but
at the build-system level, all the variables remain the same. We just don't
support 'make install' in that case anymore; but the ct-ng in the working
copy can be used after a regular 'make' (or 'make all').
Help message for --enable-local updated accordingly.

Also, move kconfig.mk into the main driver - we'd want kconfig to be a sub-package

They don't make sense - using same ct-ng won't work with different versions,
so they cannot coexist in the same prefix.
Also localize other configure variables so that their usage is easier to track.

- Remove executable permissions and shebangs from the scripts that are
supposed to be invoked only via ct-ng frontent; prepend them with $(bash).
Despite what showSamples.sh said, it already has some bashisms.
- Remove --with autotools-dev and override dh_update_autotools_config

- Install bash completion where Debian (now) expects it
- Update man page to use .\" as the comment delimiter, instead of
undefined macro (."); also, minor text edits.
- Install kconfig.mk without execute permission.
- Remove shell wrappers from 170-localedef-fix-trampoline.patch, we
do not use that for applying patches
- Revoke execute permissions on 210-expat.sh

Some older versions of configure (including the one in GMP 4.3.2)
interpret the $ECHO environment variable as the `echo' utility to
use. CT-NG sets the variable to `:' and exports it if V=0 or V=1
is supplied, breaking the samples using such configure. This currently
includes bfin-unknown-linux-uclibc and powerpc-unknown-linux-uclibc.
Also, correct the description of the V= variable - V=0 is *not* the
default; in fact, default does not correspond to any of the V=[012]
values.

Users tend to look for the build log in the current working directory,
rather than in the toolchain's installation dir. While bundling the build
log in the toolchain installation dir is nice for distribution and review,
it can be easier to have the build log readily available in the working
directory, as it is quicker to get to it.
So, the build log stays in the working directory until the toolchain is
completely and successfully built, and then a (compressed) copy is made.
