  rust: x86: support Rust >= 1.98.0 target spec (2026-05-30 15:38:16 +0200)

----------------------------------------------------------------
Rust fixes for v7.1 (2nd)

Toolchain and infrastructure:

 - Fix 'rustc-option' (the Makefile one) when cross-compiling that leads
   to build or boot failures in certain configs.

 - Work around a Rust compiler bug (already fixed for Rust 1.98.0) thats
   lead to boot failures in certain configs due to missing 'uwtable'
   LLVM module flags.

 - Support a Rust compiler change (starting with Rust 1.98.0) in the
   unstable target specification JSON files.

 - Forbid Rust + arm + KASAN configs, which do not build.

'kernel' crate:

 - Fix NOMMU build by adding a missing helper.
