Sorry, could you give me a TL;DR for this, why this PR exists and why someone (me) should invest some time figuring this out and reviewing it? I don't mean to be rude, there's just a lot going on there, it's going to take an investment to review, and I'm not sure what problem we're solving. |

These 3 recipes are broken since Node.js v23, this pull request makes them work again. |

👌 ok, that's the context I needed. Good work I guess. I'll try and make time to have a look, but there may be others watching this that can pitch in. The summary is that building some of the toolchain gets us the builds back? |

Yes. I am running tests now, it works good at the time. I will post the result of the tests as a table later. |

Pull Request Overview
Refactors CentOS 7 build recipes for x86, x64-pointer-compression, and x64-glibc-217 to add Python 3.9/3.13, GCC 15.1, and binutils builds, unify install scripts, and modernize Dockerfiles.
- Introduces shared scripts (
installPrerequisites,installFromSourceCode) and splits version/variation logic intorun_versions.sh&run_other.sh - Refactors each
run.shfor consistent environment setup and parameterized compilation - Updates Dockerfiles for multi-platform builds, caching, and modular dependency installation

Comments suppressed due to low confidence (3)
recipes/x86/should-build.sh:12
- [nitpick] The comment mentions a GCC version range, but the test is matching Node.js versions v22.0–22.2. Update the comment to clearly describe which Node.js versions are excluded.
[[ ! "$fullversion" =~ ^v22\.[0-2]\. ]] # GCC version between 9.3 and 15.1 is required but not installed
recipes/x64-pointer-compression/should-build.sh:13
- [nitpick] This regex excludes Node.js v22.2.x, but the comment refers to GCC versions. Clarify whether you're gating on Node.js or GCC versions in the comment.
[[ ! "$fullversion" =~ ^v22\.2\. ]] # GCC version between 12.1 and 15.1 is required but not installed
recipes/x64-glibc-217/should-build.sh:13
- [nitpick] The exclusion regex is for Node.js v22.2.x, but the comment describes a GCC version gap. Update the comment to match the actual Node.js filter.
[[ ! "$fullversion" =~ ^v22\.2\. ]] # GCC version between 12.1 and 15.1 is required but not installed

This test is on its own line, so its exit status isn't combined with the other conditions. You should join all version checks with && (or use set -e) so the script only exits zero when all criteria pass.

Same as above: this standalone test isn’t AND-chained with the others, so only the last command’s result determines the script’s exit code. Combine the build filters with && to enforce all checks.

This version check is not AND-chained with the subsequent lines, so the overall exit code is only based on the final test. Use && or enable set -e at the top to combine all conditions.

If find returns no files, xargs will still run sed once and may error. Add --no-run-if-empty to the xargs invocation to skip sed when there are no matches.

As I understood Docker can run x86 without emulation on x64 platform. |

OK, just getting around to trying to grok this, it's still too big for me to do a proper review but here's some initial thoughts:
@vitaliylag are you still interested in pushing this forward, since you've put so much effort into this already? |
