[LLVMdev] Failure to compile llvm-gcc-4.2-2.7 on FreeBSD on sparc machine

Ah, sorry, I was looking into wrong sources - too much different LLVM
trees around :) It seems that someone already provided 64 bit target
data.

In this case you probably need to add proper "sparc64" target triple
recognition code, then make sure that 64 bit subtarget is selected and
fix all the sparc codegen bugs you'll see on the way (I'd expect
plenty of them since sparc backend is unmaintained).
