From 61947fc024bf18b42547d2ea4cad90184132994d Mon Sep 17 00:00:00 2001 From: Ross Burton Date: Wed, 26 May 2021 22:11:32 +0100 Subject: [PATCH] gcc: revert libstc++-gdb.py installation changes Commit dbb87d in the GCC 11 branch was intended to make the installation of this Python module more robust, but for unknown reasons the library_name in libstdc++.la in baremetal builds (for example, Zephyr) is unset, so the module is just installed as "-gdb.py". This may be a GCC bug, or a bug in our build. Until that is resolved, revert the commit to fix the packaging.
