The easiest way is just to invoke clang on the .bc file, since it
clang file.bc -o file
llc will get you native assembly, which you can assemble and link with gcc.
llc file.bc -o file.s && gcc file.s -o file
I couldn't find a way to convince llc to use MC to generate an object
file. In any case, you'll need to invoke the system linker to produce
