+Description: include legacy pre-multiarch plugin path
+ A full multiarch system requires an architecture-qualified plugin path for
+ Qt, but installed systems may still have plugins (e.g., from other
+ distribution packages) in another pre-multiarch directory.  When constructing
+ the plugin path, include both the configured plugin path and a plugin path
+ with the architecture triplet stripped out.
