It has been accidentaly broken since early 2014 (and especially
 in 8.5), no easy repair, I won't devote any more hours to this stuff.
 Moreover no one seems to care apart from Emilio, but he's ok to work
 on this in a separate repository or branch.
 I left a dev/doc/ocamlbuild.txt file with a few words about this
 experiment.

 * Import of Coq_config via myocamlbuild_config.ml, instead of my get_env
 * As a consequence, we enrich this Coq_config with stuff that was
   only in config/Makefile
 * replace the big ugly find by some dependencies against source files
 * by the way: build csdpcert, with the right aliases.

I've tried to escape things properly for windows in ./configure,
but this isn't fully tested yet.

  Dealing with .vo files was harder than anticipated (issues with
  coqdep_boot and the location of the .v files). Current solution
  cannot compete for a beauty prize, but well.

  Several other issues remain (see top and bottom of myocamlbuild.ml)
  - For the moment the coqlib / coqsrc in Coq_config is to be
    hacked by hand to add _build/ in it.
  - Parallelism is a "no go" for the moment. Ocamlbuild accepts
    a -j option, but it has almost no effect experimentally.
    (but at least it doesn't take more time than make -j1,
     i.e. about 14 min here, instead of about 7 for make -j2)
  - After a first full build, ocamlbuild is awfully slow
    to detect that nothing has to be redone (1 min 25 here)

  To be continued...

 * a small shell script ./build to drive ocamlbuild
 * rules for all the binaries (apart from coqide and coqchk)
 * use of ocamlbuild's Echo instead of using shell + sed + awk
   for generated files
 * Makefile: remove unused STAGE1_CMO and add bin/coqdep_boot to the
   list of things to "clean"

 * generalize the use of .mllib to build all cma, not only in plugins/
 * the .mllib in plugins/ now mention Bruno's new _mod.ml files
 * lots of .cmo enumerations in Makefile.common are removed, since
   they are now in .mllib
 * the list of .cmo/.cmi can be retreive via a shell script line,
   see for instance rule install-library
 * Tolink.core_objs and Tolink.ide now contains ocaml _modules_, not
   _files_
 * a -I option to coqdep_boot allows to control piority of includes
   (some files with the same names in kernel and checker ...)

 This is quite a lot of changes, you know who to blame / report to
 if something breaks.

 ... and last but not least I've started playing with ocamlbuild.
 The myocamlbuild.ml is far from complete now, but it already allows
 to build coqtop.{opt,byte} here. See comments at the top of
 myocamlbuild.ml, and don't hesitate to contribute, either for completing
 or simplifying it !
