Regression: AppImage fails to run, GLIBCXX_3.4.26 not found

[Thalhammer]

Quick summary

Newer versions of the prebuilt app images fail to run on LTS distributions.

Details

Expected: AppImage works
Reality: rpcs3: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version GLIBCXX_3.4.26 not found (required by rpcs3)

We had this problem before in #3666.
I did some diging in the archived versions and it looks like the bug was reintroduced by #7459 which was merged 5h ago and affected every build after 0.08-9546, which is the last version that works for me.
