So if one wants to use the LLVM system as a cross compiler, one
has to configure llvm-gcc as a cross compiler? Fair enough, I guess.

So I assume this also means that while getelementptr insulates
llvm byte code from the details of target specific address calculations,
the target back end has to agree with gcc on how much space values
of each data type consume.
