Unfortunately, it's not possible to disable expiration age explicitly using llvm-lto. The interface it uses ignores attempts to set any of the cache options to 0, thus making it impossible to disable them completely if they are already set (and the expiration age is set by default). I don't know why the interface is this way, but it was a deliberate decision made some time ago.
