We have been building the multi threaded zstd target. This requires that
anything that links with lzstd also links with lpthread. On more recent
systems this is fine because lpthread is part of GNU libc so the
-pthread option is a no-op but on other systems this will cause GCC to
either fail to build or to silently disable zstd compression. By
building the libzstd.a-nomt-release we can be compatible with older GCC
versions and ensure that support for zstd is not silently dropped.

Since commit 16c6cc99 ("Save the toolchain configuration to its own
file, as an auto-extracting shell script:") we've been saving the
configuration as a self extracting script. This is a little non-obvious
as it looks like it should be a regular file but the bzipped payload
means it can be easily inspected. It may also cause alarm for users who
should rightly be suspicious of unexpected binaries that get shipped
along with packaged toolchains. It also assumes that bzip2 (or at least
bzcat) is available on the machine running the toolchain.
Instead of the self extracting shell script save the config as a regular
compressed file with an obvious file extension.

gold uses g++ to link which doesn't recognise -all-static. It appears as
if -static should work for both libtool and g++ but for some reason it
doesn't. Remove the restriction that gold can't be included in a static
toolchain. When a static toolchain is requested pass
--with-gold-ldflags=--static to configure. Finally build gold separately
so it does not get the extra_make_flags which may contain -all-static.

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.

Both D and GNAT have their own runtimes (resp. libphotos and libada).
It is still possible to build the compiler proper without any runtime,
and have an external runtime installed later. This is most commonly
found in embedded systems.

In canadian builds, the target toolchain running on the build
machine is not compiling and installing target Newlib. Thus it
cannot by itself link target executables. This results in
errors for gnuprumcu package when its configure script attempts
to test the compiler:
.../ld: cannot find crt0.o: No such file or directory
configure:3738: error: C compiler cannot create executables
Fix by passing the host toolchains's sysroot in target CFLAGS.
While at it, also add a missing passing of target LDFLAGS.
Successfully tested the following canadian builds:
x86_64-unknown-linux-gnu,pru
x86_64-w64-mingw32,pru

This reverts commit 57f5909285. This was
originally added so that a toolchain could be built on a newer system but
run on an older one. With the benefit of hindsight that is probably the
wrong approach. The best way of achieving that goal would be to use
docker/podman container to provide an environment that is the same as
the oldest supported system and build inside that. The resulting
toolchain should be compatible with the old system and the new one.

Starting from GDB 11.x, gmp is needed as a dependency to build full gdb.
And by default build system of native GDB will try to link with libgmp
of the build host. And to make sure that doesn't happen we need to
specify location of the target's sysroot so that library search starts
from there. Which we do in that change.

statically. Add a new internal flag GDB_CC_LD_LIBTOOL and use this to

libgccjit is still under development and, despite its name, may also be used for
ahead-of-time compilation.
Documentation can be found on the gcc website:
https://gcc.gnu.org/onlinedocs/jit/internals/index.htmlhttps://gcc.gnu.org/wiki/JIT
With this change it's possible to enable the building of the libgccjit. It's
enabled as a language (with --enable-languages=jit) even if not a language
frontend at all.
The main changes are related to the requirement of having everything host side
built as Position Independent Code (PIC) with --enable-host-shared. GCC has the
needed logic for building its dependencies (mpc, gmp, mpfr, ...) correctly when
built "in-tree", which is not the case with crosstool-ng (see
