Starting with version 13.x, the mingw headers will define the value of
NTDDI_VERSION, based on the value of _WIN32_WINNT, if that version is <
Windows 10. Given that libevent was undefining our _WIN32_WINNT, and
redefining it to a value < Windows 10 (0x0501), NTDDI_VERSION was also
being defined to that value, leading to functions not being exposed in
the mingw-w64 headers; see here:
9c2668ef77/mingw-w64-headers/include/iphlpapi.h (L36-L41).

When using CMake policies 3.14 and below, the `export(PACKAGE)` command
by default populates the user package registry, which is stored outside
the build tree. Setting the `CMAKE_EXPORT_NO_PACKAGE_REGISTRY` variable
disables this side effect.
In CMake 3.15 and later, this behavior is disabled by default, and the
variable has no effect.

When building depends on FreeBSD/OpenBSD `aarch64`, the host compilers
default to `default_host_{CC,CXX}`, which resolves to `gcc`/`g++`. This
is incorrect on these systems, where Clang is the default system
compiler.

Nix patches cmake to remove the root directory `/` from
`CMAKE_SYSTEM_PREFIX_PATH`:
428b49b28e/pkgs/by-name/cm/cmake/001-search-path.diff (L10)
Without this, and when using the toolchain for depends builds, cmake's
`find_path()` and `find_package()` do not know where to find
dependencies, causing issues like:
https://github.com/bitcoin/bitcoin/issues/32428
Adding this path back via CMAKE_PREFIX_PATH is harmless on other
systems, and fixes the toolchain for Nix users.
We append the `/` dir a maximum of once, as the toolchain may be called
repeatedly during builds.

On OpenBSD, the `sha256` command by default outputs hashsums on files in
"BSD" mode, looking like this:
$ sha256 ~/.vimrc
SHA256 (/home/thestack/.vimrc) = 6ba69d100e8c5ca0488ded6293d4e5f740a6a5d5ace96cbcf0599c18d27389e4
This is not compatible with our depends commands, which expect the
hashes to be on the first column (to be extracted via `cut -d" " -f1`).
Fix this by switching to GNU mode output, looking like this:
$ sha256 -r ~/.vimrc
6ba69d100e8c5ca0488ded6293d4e5f740a6a5d5ace96cbcf0599c18d27389e4 /home/thestack/.vimrc

According to the CMake docs, this is the correct way to setup a
toolchain file for cross-compilation using Clang. See
https://cmake.org/cmake/help/latest/manual/cmake-toolchains.7.html#cross-compiling-using-clang
Internally it looks like CMake will only take this variable into account
if it detects the compiler to be Clang, so this shouldn't effect other
builds, but in the case of our Apple cross builds, we'd end up with a
duplicated `--target=arm64-apple-darwin` on the compiler line, given we
are already setting `--target` for Darwin builds.
Would fix#31748.

Similar to #31840, currently our Linux toolchain file contains:
```bash
set(CMAKE_AR "aarch64-linux-gnu-ar")
set(CMAKE_RANLIB "aarch64-linux-gnu-ranlib")
set(CMAKE_STRIP "aarch64-linux-gnu-strip")
set(CMAKE_OBJCOPY "aarch64-linux-gnu-objcopy")
set(CMAKE_OBJDUMP "")
```
`objdump` is currently only used for the macOS cross build, where it's
`llvm-objdump`, but we should be consistent in producing a toolchain
file that points to actual tools, rather than leaving variables unset.

b28917be36 depends: Make default `host` and `build` comparable (Hennadii Stepanov)
Pull request description:
To detect cross-compiling, the host and build platforms are compared. The `build` variable is always an output of `config.sub`, but the `host` is not. This can lead to false results. For example, on OpenBSD:
- host=amd64-unknown-openbsd7.5
- build=x86_64-unknown-openbsd7.5
This PR sets the default value of the `host` variable to the value of `build`, ensuring cross-compiling won't be triggered when the `HOST` variable is not set.
This PR fixes needless triggering of cross-compiling for CMake-built packages in depends on OpenBSD due to this code:eb85cacd29/depends/funcs.mk (L193-L197)
No changes in Guix build.

`objcopy` isn't currently used for the Darwin build (only for Linux and
splitting the debug symbols), but we shouldn't be producing a toolchain
file that refers to nonexistent tools.
The `-ffile-prefix-map` compiler option implicitly enables
`-fprofile-prefix-map` in GCC or `-fcoverage-prefix-map` in Clang, which
can cause issues with coverage builds.
This change ensures that only the options necessary for build
reproducibility are applied.

The `libevent` package defaults to the "Release" build type, which
overrides our per-build-type optimization flags with `-O3`.
To prevent this behavior, set `CMAKE_BUILD_TYPE` to "None", consistent
with how other packages are handled.

According to the description for pkg-config, "pkgconf is a
replacement for pkg-config, providing additional functionality
while also maintaining compatibility. This package only provides
a dependency link to the pkgconf package to help with package
upgrades. It can be safely removed."
Thus several scripts and markdown files are updated.
We use `lld` when cross-compiling for macOS, and it's version should
be tied to LLVM. However someone compiling with GCC and `-fuse-ld=lld`
would not see a cache bust if the LLVM toolchain was updated.
We don't use `mold` directly, but I'm aware of it's usage in
infrastructure, along with depends, used to test the project.
The depends cache should be busted when flags change, the same as any
other tooling change. Id also like to start passing *FLAGS into depends
inside the Guix env, which, without this change, doesn't bust the cache.
On FreeBSD, the `shasum` utility is provided by the `perl5` port, which
is not part of the base system and must be installed separately.
Note that this requirement is currently not documented in
`depends/README.md`.
This change switches to using the `sha256sum` utility, which is included
in the base system.
This change resolves an issue where a missing space caused the value of
the `build_AR` variable to be concatenated with the "NM=" string. This
resulted in subsequent calls to `${AR}` and `${NM}` failing.
