kbuild: dummy-tools: avoid tmpdir leak in dummy gcc
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") Signed-off-by: Ondrej Mosnacek <omosnace@redhat.com> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
