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

The patch is incorrect and the problems you're seeing are caused by
your patch, since sparc != sparc64.
In LLVM sense "sparc" means "sparc with ILP32 architecture model",
llvm does not support anything 64 bit in sparc world.

Indeed, LLVM assumes that pointer size is 32 bits (since it's 32 bit
sparc), but gcc - definitely not.
