This is to accomodate migration to (and ongoing support of) a new installed-app file topology, in which APK files are placed in /data/app/$PACKAGE-rev/, there is a canonical-path symlink /data/app/$PACKAGE/ -> /data/app/$PACKAGE-rev/, and the native libraries exist not under a top-level /data/app-lib/$PACKAGE-rev hard directory, but rather under /data/app/$PACKAGE/lib (when referenced by canonical path).
