depends: latest config.sub
What changed, and why it matters
This commit updates a single helper script used during Bitcoin Core's build process. The script, called config.sub, comes from the GNU project and is responsible for recognizing different operating systems and CPU types when compiling software. The update adds support for newer or less common platforms (for example, Ironclad, Tock, Banan OS, Apple simulator targets, and the arm64_32 CPU) and fixes a duplicate entry. There is no indication this change fixes a security vulnerability or introduces malicious behavior; it is a routine dependency refresh.
No security action required. Treat as a normal build-system maintenance update. Reviewers may verify the file matches the upstream GNU config.sub version if desired.
Security signals we found
No security-relevant code modified
Routine upstream dependency refresh
No changes to consensus, cryptography, networking, or wallet modules
Evidence from the diff
The commit refreshes depends/config.sub to the latest upstream GNU config.sub (timestamp 2025-07-10). The diff is limited to platform-tuple recognition logic: adding ironclad-mlibc, tock, banan_os, ios/tvos/watchos-simulator, arm64_32, and intelgt; removing a duplicated ‘siemens’ line; and updating copyright years and Emacs local variables. No Bitcoin Core consensus, networking, wallet, or cryptographic code is touched. No security-relevant change is evident from the diff.
