From aac289653fa5adf9e9985e4912c1d24a3e8cbab2 Mon Sep 17 00:00:00 2001 From: Ondrej Mosnacek Date: Mon, 11 Jul 2022 14:09:23 +0200 Subject: 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.

We currently don't handle it, so this results in PPC_LONG_DOUBLE_128 not being in super-config generated by dummy-tools. So take this into account in the gcc script and preprocess __LONG_DOUBLE_128__ as "1".
