lang/ocaml: Caution against 5.x updates

Log message:
lang/ocaml: update to 4.14.2.

pkgsrc changes:

- Correct patch-runtime_sak.c, which had been doing the wrong thing
to fix ctype abuse.

- Makefile.common is no longer used by anything else; note that
(removing it is for a future not-just-maintenance change)

Upstream changes:

Runtime system:

    #11764, #12577: Add prototypes to old-style C function definitions
and declarations. (Antonin Décimo, review by Xavier Leroy and Nick
Barnes)

    #11763, #11759, #11861, #12509, #12577: Use strict prototypes on
primitives. (Antonin Décimo, review by Xavier Leroy, David Allsopp,
Sébastien Hinderer and Nick Barnes)

    (breaking change) #10723: do not use -flat-namespace linking for
macOS. (Carlo Cabrera, review by Damien Doligez)

    #11332, #12702: make sure Bool_val(v) has type bool in C++ (Xavier
Leroy, report by ygrek, review by Gabriel Scherer)

Build system:

    #11590: Allow installing to a destination path containing spaces.
(Élie Brami, review by Sébastien Hinderer and David Allsopp)

    #12372: Pass option -no-execute-only to the linker for OpenBSD >=
7.3 so that code sections remain readable, as needed for closure
marshaling. (Xavier Leroy and Anil Madhavapeddy, review by Anil
Madhavapeddy and Sébastien Hinderer)

    #12903: Disable control flow integrity on OpenBSD >= 7.4 to avoid
illegal instruction errors on certain CPUs. (Michael Hendricks, review

recursive types. (Jeremy Yallop, review by Gabriel Scherer and Jacques

    #12513, #12518: Automatically enable emulated fma for Visual
Studio 2019+ to allow configuration with either

emit a warning). (David Allsopp, review by Nicolás Ojeda Bär)

Log message:
lang/ocaml/ocaml.mk: Also set MAKE_ENV for !DUNE_BUILD_PACKAGES

There is an if, and two build commands, which are mostly the same, but
with differences for [mysterious dune package stuff].  The
non-dune-package arm of the if didn't set the MAKE_ENV.  I'm calling
that a bug and adding it.

I've been running with this for a while, building various things, and
it seems ok.  Proposed on tech-pkg with no objections and one positive
comment.  If this breaks things for you, feel free to revert without
asking me, and then you get to be in charge of making ocaml work.

Log message:
lang/ocaml: let this build for NetBSD powerpc before 9.99.99 too.

...by enabling --enable-imprecise-c99-float-ops in those cases,
fma(3) was added to powerpc between 9.99.98 and 9.99.99.

Log message:
ocaml: Needs imprecise-c99-float-ops to build on NetBSD/arm

Log message:
lang/ocaml: Add workaround for NetBSD/i386 build

The build errored with:
  configure: error: fma does not work, enable emulation with \ 
--enable-imprecise-c99-float-ops
and thus that arg is passed to configure.

With the change, ocaml builds, and that unison builds and works.

(No change on any other platform.)
