Unrolled build for rust-lang#126707

Rollup merge of rust-lang#126707 - ferrocene:hoverbear/fix-inaccessible-temp-dir, r=jieyouxu

Pass target to inaccessible-temp-dir rmake test

This PR circles back to do the target specific changes in `inaccessible-temp-dir` from rust-lang#126355. Specifically, this repairs the test on `riscv64gc-unknown-linux-gnu`. (The failure can be viewed in rust-lang#126641 -> https://github.com/rust-lang/rust/actions/runs/9571149616/job/26387537888?pr=126641)

We removed this change from rust-lang#126355 to avoid a merge conflict with rust-lang#126279. (...and, because I hoped that would fix the test instead, but it did not.)

## Testing

> [!NOTE]
> `riscv64gc-unknown-linux-gnu` is a [**Tier 2 with Host Tools** platform](https://doc.rust-lang.org/beta/rustc/platform-support.html), all tests may not necessarily pass! This PR is specifically about the `inaccessible-temp-dir` rmake test.

You can test out the job locally:

```sh
DEPLOY=1 ./src/ci/docker/run.sh riscv64gc-gnu
```

`DEPLOY=1` helps reproduce the CI's environment and also avoids the chance of a `llvm-c/BitReader.h` error (detailed in rust-lang#85424 and rust-lang#56650).
