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.
36b6f36ac4 build: require sqlite when building the wallet (Sjors Provoost)
Pull request description:
Require that sqlite is available in order to compile the wallet. Removes instances of `USE_SQLITE` since it is no longer possible to not have sqlite available.
The `NO_SQLITE` option is dropped from depends.
This is another step towards dropping the legacy wallet, extracted from #31250.

This only existed to workaround a (iirc libtool related) windows issue
that only occured when compiling without hardening. We no-longer use
libtool, and I can no-longer create the failure.
d9c8aacce3 depends, refactor: Avoid hardcoding `host_prefix` in toolchain file (Hennadii Stepanov)
Pull request description:
This PR allows the entire `depends/<host_prefix>` directory to be relocatable.
Only `libevent` package configuration files are non-relocatable for the version `2.1.12-stable` we use now. However, this issue has been fixed upstream in 1f1593ff27 and friends.
Fixes https://github.com/bitcoin/bitcoin/issues/31050.

Pull request description:
Continues #30005. Closes #17012..
This PR adds PCP (Port Control Protocol) from [RFC6887](https://datatracker.ietf.org/doc/html/rfc6887). This adds, in addition to the existing IPv4 port mapping (which now uses PCP, with fallback to NAT-PMP), support for IPv6 pinholing-that is, opening a port on the firewall to make it reachable.
PCP, like NAT-PMP is a simple UDP-based protocol, and the implementation is self-contained, so this gets rid of lthe libnatpnp dependency without adding a new one. It should otherwise be a drop-in replacement. NAT-PMP fallback is implemented so this will not make router support worse.
For now it is disabled by default, though in the future (not in this PR) we could consider enable it by default to increase the number of connectable nodes without adding significant attack surface.
To test:
```bash
bitcoind -regtest -natpmp=1 -debug=net
```
(most of the changes in this PR are, ironically, removing the libnatpmp dependency and associated build system and build docs)
## TODO
- [x] Default gateway discovery on Linux / FreeBSD
- [x] Default gateway discovery on Windows
- [x] Default gateway discovery on MacOS
- [x] Either solve FreeBSD compile issue (probably upstream issue) or remove FreeBSD support
## Things to consider for follow-up PRs
- https://github.com/bitcoin/bitcoin/pull/30043#discussion_r1658764974 avoid unreachable nets (not given to -onlynet=)
- https://github.com/bitcoin/bitcoin/pull/30043#discussion_r1658949236 could announce an addr:port where we do not listen (no -bind)
- https://github.com/bitcoin/bitcoin/pull/30043#discussion_r1684368824 could announce the wrong port because it uses GetListenPort()
- https://github.com/bitcoin/bitcoin/pull/30043#discussion_r1679709347 if we requested one port but another was assigned, then which one to use in the renewal?
- https://github.com/bitcoin/bitcoin/pull/30043#discussion_r1772017020 Use `GetAdapterAddresses` to discover local addresses for Windows

In the Guix environment, `${BASEPREFIX}/${HOST}/native/bin` is added to
the `PATH` environment variable, causing CMake to search for package
configurations in the `native` subdirectory first.
Explicitly specifying the top-priority search prefixes for the
`Libmultiprocess` and `LibmultiprocessNative` packages resolves the
issue.
