Comment:

 For reference, the last major change to the handling of *_stub.c files was
 in:
 {{{
 commit 7b0ff1792d699ff02a604163c9ccf4a98a1ca3eb
 Author: Simon Marlow 
 Date:   Mon Jan 31 10:32:24 2011 +0000

     Merge _stub.o files into the main .o file (Fixes #3687 and #706)
     Now GHC still generates the _stub.c files, but the object file is
     automatically merged into the main .o file for a module.  This means
     that build systems (including GHC's own) no longer need to worry about
     looking for _stub.o files and including them when linking.

     I had to do lots of refactoring in DriverPipeline to make this work;
     now there's a monad to carry around all the information, and
     everything is a lot tidier.

     The _stub.c is now created as a temporary file and removed after
     compilation (unless the -keep-tmp-files flag is on).
