Merge bitcoin/bitcoin#22244: devtools: Correctly extract symbol versions in symbol-check 
e8cd3700ee devtools: Integrate ARCH_MIN_GLIBC_VER table into MAX_VERSIONS in symbol-check.py (W. J. van der Laan)
a33381acf5 devtools: Add xkb version to symbol-check (W. J. van der Laan)
19e598bab0 devtools: Fix verneed section parsing in pixie (W. J. van der Laan)

Pull request description:

  I misunderstood the ELF specification for version symbols (verneed): The `vn_aux` pointer is relative to the main verneed record, not the start of the section.

  This caused many symbols to not be versioned properly in the return value of `elf.dyn_symbols`. This was discovered in #21454.

  Fix it by correcting the offset computation.

  - xkb versions symbols (using the prefix `V`), as this library is used by bitcoin-qt, add it to the valid versions in `symbol-check.py`

  This unfortunately brings to light some symbols that have been introduced since and weren't caught (from a gitian compile of master):

  ```

Repository Tools

Developer tools

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.

Seeds

Utility to generate the pnSeed[] array that is compiled into the client.

Build Tools and Keys

Packaging

The Debian subfolder contains the copyright file.

All other packaging related files can be found in the bitcoin-core/packaging repository.
