Comment:
- Might as well also bring over the `--with-librtmp` fix [from the other upgrade PR](https://github.com/void-linux/void-packages/pull/37823/files#diff-21f6fba8aff08b5310a01f29fc9a03295cb7c5fa0ad5474cf7e1c38b482baac6R7) that's now closed, that is [the correct flag as per upstream configure.ac](https://github.com/curl/curl/blob/curl-7_84_0/configure.ac#L2215-L2218).
- Please also update `chroot-curl` so that `armv6l-musl`, `armv7l` and `aarch64*` pass CI.
- `i686` test failure should also perhaps be looked into.
