[vlc-devel] [PATCH 3/3] contrib: rav1e: disable for iOS

[Alexandre Janniaux]

This is a temporary workaround, aiming at solving the linkage issues
with rav1e on iOS targetting arm64. The issue doesn't happen on armv7
because rust support is disabled for it. Note that it happens at link
time, so it needs --enable-shared from the build script to reproduce.

    ../extras/package/apple/build.sh \
        --arch=arm64 \
        --sdk=iphoneos \
        --enable-shared
