kbuild: rust_is_available: check that output looks as expected
The script already checks for `$RUSTC` and `$BINDGEN` existing and exiting without failure. However, one may still pass an unexpected binary that does not output what the later parsing expects. The script still successfully reports a failure as expected, but the error is confusing. For instance: $ RUSTC=true BINDGEN=bindgen CC=clang scripts/rust_is_available.sh scripts/rust_is_available.sh: 19: arithmetic expression: expecting primary: "100000 * + 100 * + " *** *** Please see Documentation/rust/quick-start.rst for details *** on how to set up the Rust support. *** Thus add an explicit check and a proper message for unexpected output from the called command. Similarly, do so for the `libclang` version parsing, too.
