From: Harish Sadineni<[email protected]>
Add initial support for building the Linux kernel with Rust enabled:
- Introduce `rust.cfg rust-samples.cfg rust-debug.cfg` to set Rust-related
kernel config options, including:
- `CONFIG_RUST=y`
- Rust sample modules and developer checks (overflow/debug assertions)
- Update `linux-yocto_${PV}.bb` to:
- Append `rust.scc rust-samples.scc` to `SRC_URI` and `KERNEL_FEATURES`
when sending non-RFC version, we will send kernel-config-fragment to the
yocto-kenrel-cache

I suspect that we want to pull in _only_ rust.scc by default.
Do you agree Harish?
This is fine for now and can be fixed once the fragments are merged in
y-k-cache.
