// extern function binding (FFI-linkage stream, Phase 1): bind libc's `abs`
// directly via the bare `extern` linkage modifier — no `extern`, no
// `#library`. `extern` ⇒ external linkage + C ABI + no sx ctx; the symbol
// resolves against the default-linked libc at link time. The sx name `abs`
// IS the C symbol (no rename — the `extern LIB "csym"` forms land in 1.2).
