bistromathic: beware of portability of readline

Browse Source 
Don't try to build bistromathic if we don't have readline.
Reported by Bruno Haible.
https://lists.gnu.org/r/bug-bison/2020-05/msg00028.html

* configure.ac (ENABLE_BISTROMATHIC): New.
* examples/c/bistromathic/local.mk: Use it.
* examples/c/bistromathic/bistromathic.test: Exit 77 for skip.
