Ayke van Laethem 9505b5cb66 [AVR] Do not use divmod calls for bigger integers ...

The avr-libc provides *divmodqi4, *divmodhi4, and *divmodsi4 functions,
but does not provide a *divmoddi4. Instead it provides regular *divdi3
and *moddi3 functions.

Note that avr-libc doesn't support *divti3 or *modti3 for 128-bit
integer manipulation.
