Subject: [PATCH] Enable rquickjs bindgen against the correct Apple SDK per
 target
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

rquickjs-sys has no prebuilt FFI bindings for iOS/tvOS targets, so
bindgen needs the matching SDK sysroot (iphoneos/iphonesimulator/
appletvos/appletvsimulator) and clang target triple per cross-compiled
target, or it silently uses the host's own headers and fails. Unverified
here — no Xcode/macOS available in this environment; needs confirming
on a real Mac before relying on it.
