Unrolled build for rust-lang#126424

Rollup merge of rust-lang#126424 - Enselic:sort-target-features, r=lqd

 Also sort `crt-static` in `--print target-features` output

I didn't find `crt-static` at first (for `x86_64-unknown-linux-gnu`), because it was put at the bottom of the large and otherwise sorted list.

Fully sort the list before we print it.

Note that `llvm_target_features` starts out and remains sorted and does not need to be sorted an extra time.

On my machine the diff is just:

```

I couldn't find a ui test that tested this output. Let's see if CI finds a regression tests.
