rust: kbuild: pass `-Zunstable-options` for Rust 1.95.0
[ Upstream commit 0a9be83e57de0d0ca8ca4ec610bc344f17a8e5e7 ]
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.
