/* Given pointers to the DEBUG_INFO and DEBUG_ABBREV sections, and
   their corresponding sizes, and whether the object file is
   LITTLE_ENDIAN or not, look at the compilation unit DIE and
   determine its NAME, compilation directory (in COMP_DIR) and its
   line number information offset (in STMT_LIST).  NAME and COMP_DIR
   may be NULL (especially COMP_DIR) if they are not in the .o file;
   STMT_LIST will be (uint64_t) -1.

   At present this assumes that there's only one compilation unit DIE.  */
