From: Ondrej Mosnacek <omosnace@xxxxxxxxxx> commit aac289653fa5adf9e9985e4912c1d24a3e8cbab2 upstream. When passed -print-file-name=plugin, the dummy gcc script creates a temporary directory that is never cleaned up. To avoid cluttering $TMPDIR, instead use a static directory included in the source tree.
