Pull Rust fixes from Miguel Ojeda:
 "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"
