rust: rebuild

[filnet]

Building the latest Rust on CLANG32 fails. See #20397.

I wan't to confirm that it could be related to the toolchain by rebuilding the currrent version.

[filnet]

My attempt at rebuilding Rust 1.76.0 (see #20404) failed on all platforms with crazy errors like:

   68 | const SMALL_POW5: [(u64, usize); 3] = [(125, 3), (15625, 6), (1_220_703_125, 13)];
     |                                  -    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ expected an array with a fixed size of 0 elements, found one with 3 elements
     |                                  |
     |                                  help: consider specifying the actual array length: `3`
     |
     = note: expected array `[(u64, usize); 0]`
                found array `[(u64, usize); 3]`

It also emitted these warnings while building the bootstrap:

 WARNING: The `change-id` is missing in the `config.toml`. This means that you will not be able to track the major changes made to the bootstrap configurations.
NOTE: to silence this warning, add `change-id = 118703` at the top of `config.toml`
