#36589 [32.x] Guix related backports

Backports Guix build configuration updates from master to the 32.x maintenance branch. It bumps the Guix time-machine commit, skips tests that fail during native builds on riscv64, explicitly declares python-setuptools, and updates certvalidator for Python 3.12 compatibility.

Problem: Deterministic release binaries cannot be built natively on RISC-V hardware on the 32.x branch due to package test failures and Guix time-machine limitations. In addition, updating to Python 3.12 broke Guix builds requiring setuptools and the test loader in certvalidator.

Evidence of importance:

• Commit a5e6a09956 notes it 'is necessary to unblock building on RISC-V systems' and fixes issue #36232.
• Commit 58938225a1 explains that python-lief and nsis-x86_64 transitively pull in packages whose tests fail when building natively on riscv64.
• PR description states: 'These backports re-enable building release binaries on RISC-V hardware.'

Scope: The 4 commits in the PR only touch 4 Guix files (+42/-11), but the diff provided against the merge base includes numerous unrelated branch commits from 32.x vs master.

Risk of a mistake: medium (build). Mistakes in Guix manifests or time-machine revisions affect release binary reproducibility and builder toolchains.

Ready

Nothing known that would invalidate a review now.

Waiting on (from the thread read):

• reviewer: review and verification of backports and Guix build results 2026-10-24

Crickets

no substantive comment either way

Thread notes: Author provided Guix build outputs on x86_64 and riscv64 confirming matching hashes.

Objections, suggestions, and questions: none recorded.
