I've never checked the correctness of what the AVR target info produces.
It's basically a patchwork of other targets like PIC16 and MSP430. There
isn't much clang documentation for creating a port (at least compared to
LLVM). I also think clang is X86 centric and has some hard coded assumptions
of the Target. There are more src files that will need to be modified in
clang but I believe Target.cpp is the minimum that allows it to be compiled.
I'll try to find some time to look into it.
