termux-packages/packages/swift/swift-ndk-23.patch

Date:   Wed Aug 25 19:31:48 2021 +0530

    [android] Update to NDK 23
    
    The latest Long Term Support NDK finally removed binutils, including the bfd/gold
    linkers and libgcc. This simplifies our Android support, including making lld the
    default linker for Android. Disable three reflection tests that now fail, likely
    related to issues with swift-reflection-dump and switching to lld.
