It's odd only if you don't consider the details. Emacs finds the rest of itself by consing Lisp strings, but that technique is unusable when looking for the pdump file, because we must find it before we can allocate memory etc., so we could set the heap flags correctly. See the comments in 'main'. It's a typical bootstrap problem. Solution is surely possible, it's just that it isn't "more of the same", i.e. we cannot simply reuse the code which finds, say, data-directory and similar.
