--- Comment #16 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I ran into this too for a cross to aarch64 with the trunk.


TARGET=aarch64-linux-gnu
../configure --prefix=/usr --host=${TARGET}

`aarch64-linux-gnu-gcc -v` output:
```
Using built-in specs.

```

I will try to set CXX as suggested in a second.
