(Patch by Adrien Nader!)

This is a partial revert of revision 14168 which caused issues when
bootstrapping the compiler. Since these directories don't take long to
build, we can always use a byte-compiled compiler.

Bootstrapping and more generally working on the compiler itself does not
play nice with trying to use the most recent compiler as soon as
possible: imagine you've just modified the compiler but in a way that
breaks it at runtime in a non-obvious way; all the files that are
subsequently built will have been built with your the compiler you will
be debugging.

v2: always build tools/ with boot/ocamlc since most executables link
    against compiler libs.

Among other files, myocamlbuild_config.ml is built in this directory.
This file defines many variables, most of which are not used and
therefore trigger this warning which is then turned into an error
through -warn-error A.
build: remove warning 32 (unused variable) in tools.

This script was built from ocamlcomp.sh.in through sed and is called
instead of "ocamlc" (for instance).
It makes it possible to switch from "ocamlc" to "ocamlc.opt" without
changing anything in the Makefiles, only calling sed.

I couldn't cleanly make it handle both a compiler for the target and for
the build. Instead I'm replacing it and doing as much as possible
directly in the Makefiles.
I hoped it would reduce the number of shell invocations, which would
speed things up quite a lot on Windows but I still had to have at least
one since it's not possible to update a make variable from inside a make
rule: i.e. it's not possible to do X=a, build a.opt and update X to be
a.opt.

These scripts sed config/Makefile in order to create shell script and
ocaml code that define the same values as the Makefile but in the
corresponding language.
The sed stuff is very difficult to understand, very brittle and
impossible to change.
Remove that altogether and use a Makefile to run commands like
[ echo FOO=$(FOO) ]. There is still some sed involved (to get the list
of variables in the config and to put rewrite the lists into a list of
commands) but much less and all the expressions are put into variables
with meaningful names with lots of comments.

For config.sh, mkconfig.sh generated lines like :
  if [ -z "${FOO}" ]; then FOO=bar; fi
The new script sets the value without checking anything.
I haven't found a reason to do things differently: if there is anything
to override, the right place to do it is after sourcing the shell
script. In any case, I haven't seen any such use.

The mkconfig.sh file also set "WINDOWS=true/false" but the only use is
in the parallel build-system which is implemented in build/ and uses
ocamlbuild as much as possible, and it's going away so it's useless to
set it too.
