Hmm. You are implying that the elc built for 32 bit emacs are identical
to the elc built for 64 bit emacs. 

Is that true? I would have guessed that most objects are either
32 bit or 64 bit; elisp manual 3.1 says the integer range depends on the
machine, and pointers should also.

If they are the same, then you should be able to write a script that
does:

1) parallel make to build elc using 32 bit
2) parallel make to build everything else, both 32 bit and 64 bit.
