The reason I added these little case macros, is that I find other backend targets have, as shown in the compiler-rt's CMakefile, https://github.com/llvm/llvm-project/blob/main/compiler-rt/cmake/Modules/CompilerRTUtils.cmake#L155 I think we need not strictly follow avr-gcc's way, my final goal is making clang+llvm+compiler-rt+lld fully functional and can replace avr-gcc toolchain.
