error: unknown argument: '-package-name' with toolchains < 5.9

[krzyzanowskim]

Is it reproducible with SwiftPM command-line tools: swift build, swift test, swift package etc?

• Confirmed reproduction steps with SwiftPM CLI.

Description

Can't use toolchains < 5.9 to build swift package, after upgrade to Xcode 15 on macOS

Expected behavior

OnlineSwiftPlayground/OnlinePlayground/OnlinePlayground-5.7-RELEASE on master ❯ swift build

Steps to reproduce

1. Install Xcode 15
2. Download toolchain https://download.swift.org/swift-5.7-release/xcode/swift-5.7-RELEASE/swift-5.7-RELEASE-osx.pkg
3. use the downloaded toolchain to build a package

I use https://github.com/krzyzanowskim/OnlineSwiftPlayground to automate steps.
