Checking Rust Support with the rustavailable Target
The kernel ships a one-command self-check that answers the question 'is my machine able to build Rust kernel code yet?'. It inspects your compiler version, the standard library source, bindgen and the rest, and prints the exact missing piece if something is wrong. Running it takes seconds and replaces guessing at a long build failure. It is the first command to run after setting up a toolchain, and the first one to re-run when something breaks.
