Then please explain how come pexecute prints that message.

I assume you're running on some Unix flavor, probably GNU/Linux, so
the last variant of pexecute is used.  The only situation in which
this variant of pexecute() prints install_error_msg is after
attempting to exec() the program:

    case 0: /* child */
[snip]
      /* Exec the program.  */
      (*func) (program, argv);

      /* Note: Calling fprintf and exit here doesn't seem right for vfork.  */
      fprintf (stderr, "%s: ", this_pname);
      fprintf (stderr, install_error_msg, program);
      fprintf (stderr, ": %s\n", xstrerror (errno));

func is either execv or execvp.  this_pname is the name of the current
program (gcc); program is the name of the program to be exec()ed
(collect2).  I can't think of any way collect2 might arrange for the
process that exec()ed it to print that error message.  How did you
make sure that collect2 was properly exec()ed?
