kbuild: dummy-tools: avoid tmpdir leak in dummy gcc

Browse Source 
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.
