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.
Fixes: 76426e238834 ("kbuild: add dummy toolchains to enable all cc-option etc. in Kconfig")
