 mint: fix build for macOS 10.14 and 10.15

 mint's Makefile assumes the --arch flag is available on the `swift
 build` command, which was added in Swift 5.3 / Xcode 12. This causes
 builds to fail on machines with an older version of Xcode, even if
 mint actually supports the Xcode version being used.
