--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
For me it has:
```
configure:25857: checking assembler for .base64
configure:25867: /usr/bin/as --64  -o conftest.o conftest.s >&5
conftest.s: Assembler messages:
conftest.s:2: Error: unknown pseudo-op: `.base64'
configure:25870: $? = 1
configure: failed program was
        .section .rodata
        .base64
"Tm9uIHB1ZG9yIGVzdCBuaWwgc2NpcmUsIHB1ZG9yIG5pbCBkaXNjZXJlIHZlbGxlLgo="
configure:25881: result: no

```

Are you doing a combined build?
