Tor Arne Vestbø ac43986aa5 Pass -arch when running toolchain configure test on Apple platforms
Clang doesn't automatically switch architecture just because we're
passing an iPhoneOS sysroot. In the past this resulted in a warning
about trying to link an x86_64 binary to arm64 libraries, but with
Xcode 12 this is now a hard error.
