Any package linking against libcjs on armhf therefore fails to link. Rebuilding cjs against the current mozjs makes those helpers resolve from libgcc as ordinary unversioned symbols, which fixes the problem for good. Once cjs has been rebuilt, cinnamon needs a give-back: gb cinnamon_6.6.8-2 . armhf . unstable
