Not in detail, but that file is the first thing it's using the built  
llvm-gcc4 to compile,
so something is wrong with that.  It looks like it might be  
misconfigured somehow.
That message is coming from the assembler and I suggest looking at the
assembler (.s) file, you may be able to figure it out from that.
To get that add -save-temps to the compilation line, which is this:
