I have to admit that I don't fully understand the dump/bootstrap logic
of Emacs (yet), but doesn't inhibit the following test in Frequire already
any/most uncleanliness:

      /* This is to make sure that loadup.el gives a clear picture
         of what files are preloaded and when.  */
      if (will_dump_p () && !will_bootstrap_p ())
        {
          /* Avoid landing here recursively while outputting the
             backtrace from the error.  */
          gflags.will_dump_ = false;
          error ("(require %s) while preparing to dump",
                 SDATA (SYMBOL_NAME (feature)));
        }

At least that error fires during dump ("Dump mode: pdump") when I try to
require, for example, cl-lib from a file loaded from loadup.el.
