 inline-c could benefit of the ability to tell the compiler to include some
 code in the object file of the current module.
 https://github.com/fpco/inline-c/issues/21

 This way, a module `FFI.hs` using inline-c doesn't need to produce a file
 `FFI.c` with C code, but the code can be build and included in the file
 FFI.o directly.

 For this sake, it would be needed the following TH function:
 {{{
 addModCStub :: String -> Q ()
 }}}
 which would indicate to the compiler that the C code in the given string
 needs to be built and included in the object file of the current module.
