Minimum deployment target can be set before the introduction of a moved symbol. When that happens, using the introductory version in the
$ld$previous
symbol could lead to ld not redirecting the linkage path to the original dylib, which is a mistake when running the App on newer OSs when the original dylib does exist.rdar://105181824
