 MacPorts base does use `-Wl,-syslibroot`. That's what Apple said to use
 when universal binaries started to be a thing in 10.4, and it used to work
 fine. If it changed at some point, that's annoying, but we would need to
 know what that point is so that MacPorts base can be updated to do the
 right thing, whatever the system or Xcode version.
