resolve error when attempting to link a universal library on macOS Previously attempting to link universal libraries into libraries (but not binaries) would produce an error that "File too small to be an archive". This works around this by using `object` to extract a library for the target platform when passed a univeral library. Fixes #55235 2022-06-30 15:01:38 -04:00			`extern "C" {`
