Merge bitcoin/bitcoin#29695: guix: build GCC with --enable-standard-branch-protection 
7850c5fe20 guix: build GCC with --enable-standard-branch-protection (fanquake)

Pull request description:

  This is one change extracted from #24123 (which now produces fully BTI & PAC enabled bins), which will mean that everything in depends, for Guix builds, is compiled using `-mbranch-protection=standard`.

  Turning this on by default, is similar to what we already do with `--enable-default-ssp`, `--enable-default-pie` etc.

  See: https://gcc.gnu.org/install/specific.html#aarch64-x-x

  > To enable Branch Target Identification Mechanism and Return Address Signing by default at configure time use the `--enable-standard-branch-protection` option.

  > This is equivalent to having `-mbranch-protection=standard` during compilation. This can be explicitly disabled during compilation by passing the `-mbranch-protection=none` option which turns off all types of branch protections.

Specific tools for developers working on this repository. Additional tools, including the github-merge.py script, are available in the maintainer-tools repository.

Verify-Commits

Tool to verify that every merge commit was signed by a developer using the github-merge.py script.

Linearize

Construct a linear, no-fork, best version of the blockchain.

Qos

A Linux bash script that will set up traffic control (tc) to limit the outgoing bandwidth for connections to the Bitcoin network. This means one can have an always-on bitcoind instance running, and another local bitcoind/bitcoin-qt instance which connects to this node and receives blocks from it.
