Miguel Ojeda 0a9be83e57 rust: kbuild: pass -Zunstable-options for Rust 1.95.0
Custom target specifications are unstable, but starting with Rust 1.95.0,
`rustc` requires to explicitly pass `-Zunstable-options` to use them [1]:

    error: error loading target specification: custom targets are unstable and require `-Zunstable-options`
      |
      = help: run `rustc --print target-list` for a list of built-in targets

David (Rust compiler team lead), writes:

   "We're destabilising custom targets to allow us to move forward with
    build-std without accidentally exposing functionality that we'd like
    to revisit prior to committing to. I'll start a thread on Zulip to
    discuss with the RfL team how we can come up with an alternative
    for them."

Thus pass it.
