emerge --info '=cross-arm-none-eabi/gcc-10.1.0-r2::crossdev'

Hello all,

When emerging '=cross-arm-none-eabi/gcc-10.1.0-r2::crossdev' with the 'hardened' USE flag set, I encountered a compile error of this kind:

```
sorry, unimplemented: '-fstack-check=specific' for Thumb-1
```

With `hardened` unset (disabled) the compilation works without any hicups.

Attached are
- The `emerge --info` output
- The `emerge -pqv` output
- The `build.log` file
- `gcc-build-logs.tar.bz2` as requested

Do you know where does this USE=hardened come from? It enabled stack protection by default not compatible with this particular bare-metal target.
