Because of reasons described in 9ea3424a178 we need to define
HAVE_STDARG_H before including readline otherwise macos build
fails. Honestly, I still don't fully understand the problem so I
am not going to bother you with "explanation".

How common is it for library .h files to assume autotools-style HAVE_*
and WITH_* flags are defined? I'm just wondering if this particular
failure is just one instance that's indicating a more general problem.
