devel/bison: do not suggest nls option on Darwin

The previous commit message included the following comment:

    TODO: avoid suggesting nls on macOS/x86_64 versions where bison
    will crash.

Additionally, options.mk contains a comment suggesting the crash only
occurs for versions less than or equal to approximately 11.6.  This
commit adds conditionals to options.mk to suggest the nls option only
when crashes are not expected.

Log message:
*: recursive bump for perl 5.36

Seems like that might be just 11.6?

bison: update to 3.8.2.

* Noteworthy changes in release 3.8.2 (2021-09-25) [stable]

  Fixed portability issues of bison on Cygwin.

  Improvements in glr2.cc: add support for custom error messages (`%define
  parse.error custom`), allow linking several parsers together.

Log message:
devel: Remove SHA1 hashes for distfiles

Log message:
bison: update to 3.8.1.

* Noteworthy changes in release 3.8.1 (2021-09-11) [stable]

  The generation of prototypes for yylex and yyerror in Yacc mode is
  breaking existing grammar files.  To avoid breaking too many grammars, the
  prototypes are now generated when `-y/--yacc` is used *and* the
  `POSIXLY_CORRECT` environment variable is defined.

  Avoid using `-y`/`--yacc` simply to comply with Yacc's file name
  conventions, rather, use `-o y.tab.c`.  Autoconf's AC_PROG_YACC macro uses
  `-y`.  Avoid it if possible, for instance by using gnulib's gl_PROG_BISON.

** Backward incompatible changes

  In conformance with the recommendations of the Graphviz team
  (https://marc.info/?l=graphviz-devel&m=129418103126092), `-g`/`--graph`
  now generates a *.gv file by default, instead of *.dot.  A transition
  started in Bison 3.4.

  To comply with the latest POSIX standard, in Yacc compatibility mode
  (options `-y`/`--yacc`) Bison now generates prototypes for yyerror and
  yylex.  In some situations, this is breaking compatibility: if the user
  has already declared these functions but with some differences (e.g., to
  declare them as static, or to use specific attributes), the generated
  parser will fail to compile.  To disable these prototypes, #define yyerror
  (to `yyerror`), and likewise for yylex.

** Deprecated features

  Support for the YYPRINT macro is removed. It worked only with yacc.c and
  only for tokens.  It was obsoleted by %printer, introduced in Bison 1.50
  (November 2002).

  It has always been recommended to prefer `%define api.value.type foo` to
  `#define YYSTYPE foo`.  The latter is supported in C for compatibility
  with Yacc, but not in C++.  Warnings are now issued if `#define YYSTYPE`
  is used in C++, and eventually support will be removed.

  In C++ code, prefer value_type to semantic_type to denote the semantic
  value type, which is specified by the `api.value.type` %define variable.

** New features

*** A skeleton for the D programming language

  The "lalr1.d" skeleton is now officially part of Bison.

  It was originally contributed by Oliver Mangold, based on Paolo Bonzini's
  lalr1.java, and was improved by H. S. Teoh.  Adela Vais then took over
  maintenance and invested a lot of efforts to complete, test and document
  it.

  It now supports all the bells and whistles of the other deterministic
  parsers, which include: pull/push interfaces, verbose and custom error
  messages, lookahead correction, token constructors, internationalization,
  locations, printers, token and symbol prefixes, etc.

  Two examples demonstrate the D parsers: a basic one (examples/d/simple),
  and an advanced one (examples/d/calc).

*** Option -H, --header and directive %header

  The option `-H`/`--header` supersedes the option `--defines`, and the
  directive %header supersedes %defines.  Both `--defines` and `%defines`
  are, of course, maintained for backward compatibility.

*** Option --html

  Since version 2.4 Bison can be used to generate HTML reports.  However it
  was a two-step process: first bison must be invoked with option `--xml`,
  and then xsltproc must be run to the convert the XML reports into HTML.

  The new option `--html` combines these steps.  The xsltproc program must
  be available.

*** A C++ native GLR parser

  A new version of the C++ GLR parser was added: "glr2.cc".  It generates
  "true C++11", instead of a C++ wrapper around a C parser as does the
  existing "glr.cc" parser.  As a first significant consequence, it \ 
supports
  `%define api.value.type variant`, contrary to glr.cc.

  It should be upward compatible in terms of interface, feature and
  performance to "glr.cc". To try it out, simply use

  %skeleton "glr2.cc"

  It will eventually replace "glr.cc".  However we need user feedback on
  this skeleton.  _Please_ report your results and comments about it.

*** Counterexamples

  Counterexamples now show the rule numbers, and always show ε for rules
  with an empty right-hand side.  For instance

    exp
    ↳ 1: e1       e2     "a"
         ↳ 3: ε • ↳ 1: ε

  instead of

    exp
    ↳ e1  e2  "a"
      ↳ • ↳ ε

*** Lookahead correction in Java

  The Java skeleton (lalr1.java) now supports LAC, via the `parse.lac`
  %define variable.

*** Abort parsing for memory exhaustion (C)

  User actions may now use `YYNOMEM` (similar to `YYACCEPT` and `YYABORT`)
  to abort the current parse with memory exhaustion.

*** Printing locations in debug traces (C)

  The `YYLOCATION_PRINT(File, Loc)` macro prints a location.  It is defined
  when (i) locations are enabled, (ii) the default type for locations is
  used, (iii) debug traces are enabled, and (iv) `YYLOCATION_PRINT` is not
  already defined.

  Users may define `YYLOCATION_PRINT` to cover other cases.

*** GLR traces

  There were no debug traces for deferred calls to user actions.  They are
  logged now.

** Bug fixes

*** Reused Push Parsers

  When a push-parser state structure is used for multiple parses, it was
  possible for some state to leak from one run into the following one.

*** Fix Table Generation

  In some very rare conditions, when there are many useless tokens, it was
  possible to generate incorrect parsers.

*** Counterexample Generation

  In some cases counterexample generation could crash.  This is fixed.

*** Fix Table Generation

  In some very rare conditions, when there are many useless tokens, it was
  possible to generate incorrect parsers.

*** GLR parsers now support %merge together with api.value.type=union.

*** C++ parsers use noexcept in more places.

*** Generated parsers avoid some warnings about signedness issues.

*** C-language parsers now avoid warnings from pedantic clang.

*** C-language parsers now work around quirks of HP-UX 11.23 (2003).
