Build: Provide option to suppress resourceUsage keys in AU plists

 - `AU_SANDBOX_SAFE`
   - May be either TRUE or FALSE. Adds the appropriate entries to an AU plugin's Info.plist.
 
+- `SUPPRESS_AU_PLIST_RESOURCE_USAGE`
+  - May be either TRUE or FALSE. Defaults to FALSE. Set this to TRUE to disable the `resourceUsage`
+    key in the target's plist. This is useful for AU plugins that must access resources which cannot
+    be declared in the resourceUsage block, such as UNIX domain sockets. In particular,
+    PACE-protected AU plugins may require this option to be enabled in order for the plugin to load
+    in GarageBand.
