- Use compiler-rt and picolibc instead of avr-libc. - Use ld.lld instead of avr-ld (or avr-gcc). This makes it much easier to get started with TinyGo on AVR because installing these extra tools (gcc-avr, avr-libc) can be a hassle. It also opens the door for future improvements such as ThinLTO. There is a code size increase but I think it's worth it in the long run. The code size increase can hopefully be reduced with improvements to the LLVM AVR backend and to compiler-rt.
