392f3caef6 examples: beware of the portability of flex --header-file 
The option --header was introduced in version 2.5.6.
The option --header-file was introduced in version 2.6.4.
Reported by Bruno Haible.
https://lists.gnu.org/r/bug-bison/2020-05/msg00013.html

So use --header, and do bother with versions that don't support it.

* m4/flex.m4: Check whether flex supports --header.
* configure.ac (FLEX_WORKS, FLEX_CXX_WORKS): Set to false if it doesn't.
* * examples/c/reccalc/local.mk, examples/c/reccalc/Makefile:
Use --header rather than --header-file.

825150b085 configure: don't require Flex 
Flex should not be required to build Bison or run the test suite (of
course it is needed for maintaining Bison).  Yet the Automake
conditional FLEX_WORKS does not work.

* m4/flex.m4 (_AC_PROG_LEX_YYTEXT_DECL): Since this is called
conditionally, don't define LEX_IS_FLEX here, but rather...
(AC_PROG_LEX): here.
* configure.ac: Be more cautious about possibly undefined variables.

355e5a7255 build: AC_PROG_LEX: use more readable variable names.

supports some of the Flex options, and exclusive start conditions.
Define FLEX to 'yes'/'', as AC_PROG_CC does for GCC.
