    # armv7 can't run on the x86_64 emulator, so this is a cross-compile check
    # only (build-tests/run-tests off skips the emulator entirely). The action
    # provisions the Android NDK and points the SDK at it via ANDROID_NDK_HOME;
    # a bare `swift:6.3.3` container can't build for Android because the SDK's
    # `ndk-sysroot` (semaphore.h, libc, …) is supplied by the NDK, not the
    # bundle. The action's build command already targets x86_64, so append a
    # second `--swift-sdk` for armv7 (last one wins) to retarget the compile.
