targets: clean up and unify linker scripts
...
Especially arm.ld needed some cleaning up. Other than that, I've made
sure the two linker scripts look similar where possible.

nrf: use assembly for nrf52, not nrf51
...
Slightly increase code size, but this is the more correct thing to do.

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
...
This doesn't completely work for some reason as the first character of
.data is corrupted, but otherwise it works.

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.

avr: link with the GCC runtime library
...
This allows the use of some compiler-generated builtins that are
hopefully compatible with LLVM. Example: println(uint8(foo))
Code size is unchanged normally but of course compiler builtins will
increase code size when actually used (for example with division).

targets/pca10040: support linking from within the compiler
...
This is kind of dirty with that huge list of linker params, but it works
and it produces smaller object files (probably because GCC is better
optimized for size).

This makes sure the compiler itself can build/link an ELF file that
