fa8762da62 build: ci/doc win64-cross build via nix (MarcoFalke)
fafe7205cc doc: Clarify that cygwin/msys2 are not tested/supported (MarcoFalke)
Pull request description:
Release cross-builds to win64 are done in guix. There are also docs to use Debian/Ubuntu for those cross-builds and this approach is used in CI. However, there are many problems:
* The CI is intended to mirror the guix build, but often it is not possible to find the major versions used for mingw and GCC in the guix build in the `apt` packages for an LTS distro.
* Users on older distro releases may lack released bugfixes, such as 8e06daa36d in mingw 13 (e.g. Debian Trixie with mingw 12, https://packages.debian.org/trixie/mingw-w64-x86-64-dev).
* When using the UCRT variant of the build, this uncovers bugs such as https://bugs.launchpad.net/ubuntu/+source/mingw-w64/+bug/2106420 or https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1121403.
So add a way to use nix to do the cross build. This allows to closer mimic the guix build.
Also, clarify that cygwin/msys2 are not tested/supported.

465bca734e contrib: reject divergent verify-commits history (Lőrinc)
b3d1dca338 contrib: fail on verify-commits ancestry errors (Lőrinc)
Pull request description:
**Problem:** `verify-commits.py` checks a Git commit's history for trusted signatures and tree hashes back to configured roots.
The documented workflow runs this check after fetching a commit and before checkout, proceeding only when the script succeeds.
A commit that is an ancestor of a configured root is intentionally accepted without checking earlier history.
The script also takes this success path after Git errors or for divergent commits, even though neither establishes that relationship.
**Fix:** Require Git to prove the ancestor relationship before taking this success path.
**Reproducers:** Each commit can be validated manually.
<details><summary>Manual reproducer: Git error</summary>
Run this on `master` and at this PR's head:
```bash
contrib/verify-commits/verify-commits.py 0000000000000000000000000000000000000000 && echo ❌ || echo ✅
```
`master` exits successfully without verifying the missing commit, while the PR head rejects the Git error.
</details>
<details><summary>Manual reproducer: divergent history</summary>
On `master` and at this PR's head, create an unreferenced sibling of the trusted root and run the verifier:
```bash
root=$(head -n1 contrib/verify-commits/trusted-git-root)
divergent_commit=$(git commit-tree "$root^{tree}" -p "$root^" -m 'divergent commit')
contrib/verify-commits/verify-commits.py "$divergent_commit" && echo ❌ || echo ✅
```
`master` exits successfully without verifying the sibling commit, while the PR head rejects divergent history.
</details>

de9b436ba3 depends: Switch from multilib to platform-specific toolchains (Hennadii Stepanov)
Pull request description:
Using the multilib GCC toolchain, as currently documented in [`depends/README.md`](4c1906a500/depends/README.md), has several issues, such as:
1. The [`g++-multilib`](https://packages.ubuntu.com/noble/g++-multilib) package conflicts with platform-specific cross-compiler packages. This means it is not possible to cross compile for `i686` and other platforms using the same set of installed packages.
2. The [`g++-multilib`](https://packages.ubuntu.com/noble/g++-multilib) package is not available for `arm64`:
```sh
$ sudo apt install g++-multilib
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package g++-multilib
```
3. Managing the multilib GCC toolchain requires additional code in both depends and Guix scripts.
This PR addresses all the issues mentioned above by switching from multilib to platform-specific toolchains.

Here are examples of building for different scenarions:
- Linux, `x86_64` or `arm64`, building with depends natively:
```sh
$ gmake -C depends -j $(nproc)
$ cmake -B build --toolchain depends/$(./depends/config.sub $(./depends/config.guess))/toolchain.cmake
$ cmake --build build -j $(nproc)
```
- Linux, `x86_64` or `arm64`, cross compiling for `i686-pc-linux-gnu`:
```sh
$ sudo apt install g++-i686-linux-gnu binutils-i686-linux-gnu
$ export HOST=i686-linux-gnu
$ gmake -C depends -j $(nproc)
$ cmake -B build-${HOST} --toolchain depends/${HOST}/toolchain.cmake
$ cmake --build build-${HOST} -j $(nproc)
```
- Linux, `x86_64`, cross compiling for `arm64`:
```sh
$ sudo apt install g++-aarch64-linux-gnu binutils-aarch64-linux-gnu
$ export HOST=aarch64-linux-gnu
$ gmake -C depends -j $(nproc)
$ cmake -B build-${HOST} --toolchain depends/${HOST}/toolchain.cmake
$ cmake --build build-${HOST} -j $(nproc)
```

`verify-commits.py` must not authorize checkout for a commit whose history diverges from configured trust roots.
Require proof that the commit is an ancestor of a root before skipping checks, and identify the failing root in errors.

`verify-commits.py` must not authorize checkout when Git cannot inspect the requested commit or its ancestry.
Reject ancestry command errors and validate the exact trusted root through Git before reporting success.

Otherwise the build will fail with warnings about missing Python (removed
in the next commit). However the non-gui build does not need Python.
Note that #25573 contains the same change, because the use of -static-pie
causes warnings when combined with our/CMakes own PIE handling.
Can do this now that the GUI has been split out.

Pull request description:
The C.UTF-8 locale is set by default in `guix shell`, and there is no reason to avoid it nowadays. This PR also silences superfluous warnings from Qt tools, making build logs cleaner and other issues easier to spot. For example:
```
Detected locale "C" with character encoding "ANSI_X3.4-1968", which is not UTF-8.
Qt depends on a UTF-8 locale, and has switched to "C.UTF-8" instead.
If this causes problems, reconfigure your locale. See the locale(1) manual
for more information.
```
Locales in the `guix-*` launch scripts have been updated as well for consistency with the rest of the codebase.
Additionally, the headers of the Guix scripts have been adjusted for [uniformity](https://github.com/bitcoin/bitcoin/pull/35775#discussion_r3636959268).

Using shell parameter expansion ensures that on non-Linux hosts the
build script won't pass an empty string argument to CMake. This resolves
the "Ignoring empty string" warning.
701bc2dc02 contrib: Fix NameError in signet miner gbt() (Torkel Rogstad)
Pull request description:
The logging.warning call referenced `bci["bestblockhash"]`, a variable from the calling scope `do_generate()` that is not available inside the `Generate.gbt()` method. This would crash with a NameError when getblocktemplate returned a template based on an unexpected previous block.
Use the `bestblockhash` parameter that was already being passed in and used correctly in the comparison on the line above.
The bug was introduced in 7b31332370 when the gbt logic was extracted into its own method — the if-condition was updated but the logging call was not.
