The assembler comes from binutils on Linux.

I think that was slightly confused; on OS X, the assembler is provided by
Apple in the same package (Xcode command line tools) as gcc, although it's
not part of gcc as such. (Apple doesn't use binutils, as its Mach-O object
support tends to be out of date or broken.) I don't *think* gcc is involved
with building stuff with -llvm.
