IOS x86_64 - Build fails due to libvdrtools linking errors for x84_64 IOS target

[dinbtechit]

On Mac M1, the build fails for target x86_64-apple-ios as it's not able to compile libvdrtools (indyvdr) due to linking errors.

Note - Strangely it happens only w for x84_64 IOS on a M1 mac or Intel Mac. Cross-compiling X86_64 darwin works fine on M1 Mac and vice versa.

Command:

TARGET=x86_64-apple-ios
rustup target add "$TARGET"
cargo build -r --target="$TARGET"

Error:
