When there is no rule to build a target in the makefile, make looks
for a builtin rule.
When --no-builtin-rules is specified make no longer performs this lookup.
E.g. the following in an excerpt from make -d output.
Here, make looks for a rule to build 'all'.
Considering target file 'all'.
File 'all' does not exist.
Looking for an implicit rule for 'all'.
Trying pattern rule with stem 'all'.
Trying implicit prerequisite 'all.o'.
Trying pattern rule with stem 'all'.
Trying implicit prerequisite 'all.c'.
Trying pattern rule with stem 'all'.
Trying implicit prerequisite 'all.cc'.
Trying pattern rule with stem 'all'.
Trying implicit prerequisite 'all.C'.
Trying pattern rule with stem 'all'.
Trying implicit prerequisite 'all.cpp'.
Trying pattern rule with stem 'all'.
Trying implicit prerequisite 'all.p'.
Trying pattern rule with stem 'all'.
Trying implicit prerequisite 'all.f'.
...
Many more lines like this are omitted.
Because this build system does not use make builtin rules or suffixes,
there is no benefit in having builtin rules enabled.
There are 2 benefits in having builtin rules disabled.
1. Improves performance by eliminating redundant lookups.
2. Simplifies troubleshooting by reducing the output of make -d or
make -p.
671b774d1b depends: Use $(package)_file_name when downloading from the fallback (Ava Chow)
Pull request description:
The server hosting the fallbacks uses `make download` so the files are only available with their overridden names rather than the original name on the upstream source. We should therefore also use the overridden name when downloading from the fallback.
Fixes https://github.com/bitcoin-core/bitcoincore.org/issues/1168

1aaaaa078b fuzz: Drop unused workaround after Apple-Clang bump (MarcoFalke)
fadad7a494 Drop support for EOL macOS 13 (MarcoFalke)
Pull request description:
Now that macOS 13 is EOL (https://en.wikipedia.org/wiki/MacOS_Ventura), it seems odd to still support it.
(macOS Ventura 13.7.8 received its final security update on 20 Aug 2025: https://support.apple.com/en-us/100100)
This patch will only be released in version 31.x, another 6 months out from now.
So:
* Update the depends build and release note template to drop EOL macOS 13.
* As a result, update the earliest Xcode to version 16 in CI.
* Also, bump the macOS CI runner to version 15, to avoid issues when version 14 will be at its EOL in about 1 year.
This also allows to drop a small workaround in the fuzz tests and unlocks libcpp hardening (https://github.com/bitcoin/bitcoin/pull/33462)

The https://fukuchi.org/ homepage no longer links to the source tarball,
and previously available files appear to have been removed. The homepage
now instructs users to download source tarballs from the GitHub releases
page instead.
The diff between the source trees is immaterial.
This causes IPC binaries (bitcoin-node, bitcoin-gui) to be included
in releases.
The effect on CI is that this causes more depends builds to build IPC
binaries, but still the only build running functional tests with them
is the i686_multiprocess one.
Except for Windows.
The per-host flag variables hold platform-specific defaults that are ignored
when flag environment variables are set, so it was wrong for them to contain
-std options relied on by package definitions.
Additionally, these flags (-pipe and -std=xx) will no longer be passed into
the CMake build, meaning less duplication in the build summary.
Pulled out of #31920.
f5647c6c5a depends: fix libevent _WIN32_WINNT usage (fanquake)
Pull request description:
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).
Imports a commit from usptream ([a14ff91254f40cf36e0fee199e26fb11260fab49](a14ff91254)).

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.
4f10a57671 depends: Override host compilers for FreeBSD and OpenBSD (Hennadii Stepanov)
Pull request description:
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.
To ensure proper compiler selection, this PR adopts the same approach used for `darwin`:c1d4253d31/depends/builders/darwin.mk (L12-L14)

This has a few advantages over the old method of simply copying headers:
- Installs proper cmake files which can be picked up by our buildsystem
- Only installs necessary headers, not all of boost
