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.
