...
Apparently the target of a weak symbol must be defined in the same file
as where it is used as a weak symbol.

avr: fix corrupted .data byte
...
The stack and the .data section shared the first byte, leading to
corruption of the first byte of .data.

avr: implement .data section

avr: convert initialization from asm to Go
...
This increases code size by 1 instruction (2 bytes) because LLVM isn't
yet smart enough to recognize that it doesn't need to clear a register
to use 0: it can just use r1 which is always 0 according to the
convention. It makes initialization a lot easier to read, however.
