The job requires GCC 10 because in 2023, Ubuntu provided GCC 9 by default which had a bug with vfork(). This is no longer needed on Ubuntu 26.04. |

This PR changes multiple things at once. I created other PRs to upgrade LLVM, GCC and Java to prepare this PR. See pull requests attached to #152785. |

Probably, with 26.04 you can remove libmpdec workaround from |
…ctions Update .github/actionlint.yaml to allow ubuntu-26.04 and ubuntu-26.04-arm images.

ubuntu-latest is currently Ubuntu 24.04.

As far as possible, optionally I think we could skip 3.10 if it doesn't come cleanly from the 3.11 backport. |

This PR relies on these 3 other PRs:
The GCC and Java changes have been backported to 3.13, 3.14 and 3.15 branches. The LLVM change was only backported to 3.14 and 3.15 branches. |

GH-153416 is a backport of this pull request to the 3.15 branch. |
