----------------
1. Though I expect each device family has its own optimized build of compiler-rt binary, I found most targets such as arm/x86 use unique `libclang-rt.builtins.a`. So I will follow this tradition for avr, a compitable avr binary built with the minimal instruction set is used.

2. I have to explicitly inherit `getCompilerRTPath`, since AVR can never be a host environment, the default path `$resource_dir/lib` is not suitable for AVR.
