Makefile: the .ml of .ml4 are now produced explicitely (in binary ast form)

- This way, the Makefile.build gets shorter and simplier, with a few nasty
   hacks removed.
 - In particular, we stop creating dummy .ml of .ml4 early "to please ocamldep".
   Instead, we now use ocamldep -modules, and process its output via coqdep_boot.
   This ways, *.cm* of .ml4 are correctly located, even when some .ml files
   aren't generated yet.
 - There is no risk of editing the .ml of a .ml4 by mistake, since it is by
   default in a binary format (cf pr_o.cmo and variable READABLE_ML4).
   M-x next-error still open the right .ml4 at the right location.
 - mltop.byteml is now mltop.ml, while mltop.optml keeps its name
 - .ml of .ml4 are added to .gitignore
