altos: Add 64x64 multiply. Test 64 ops for dest same as either source
The test change is to ensure that the destination may be one of the 64
bit sources.

the unsigned 32x32 multiply really does work, just use it

SDCC doeesn't provide a native 64-bit type (sigh), so
implement the minimal operations necessary for the MS5607 conversion
routine.

Something changed in the binutils-avr package which makes the linker
