Reproduced here with USE=hardened. Try it with USE=-hardened disabled. If it works i'll disable it for bare-metal profiles at least in crossdev.

Disabled in =sys-devel/crossdev-99999999 for now. Will need to do similar in toolchain.eclass.
While USE=hardened allow build to complete successfully, USE=hardened was working like a charm for 8.2.0-r6
https://github.com/gcc-mirror/gcc/commit/706dca65fda779bf270d3d7018c138cbe87f643d is in gcc since at least gcc-6: /* If we have a frame, then do stack checking. FIXME: not implemented. */ if (flag_stack_check == STATIC_BUILTIN_STACK_CHECK && size) sorry ("-fstack-check=specific for THUMB1"); It might have exposed when we fixed stack protection switch in https://bugs.gentoo.org/675050#c4
