$NetBSD: patch-ext_recode_recode.c,v 1.1 2018/12/15 17:12:44 taca Exp $

program_name is expected variable, is required by recode 3.5 and
recode 3.6 to actually work.

The config.m4 test for it is broken at least for some platforms -
it only tests if program without it compiles, but on Solaris and
MacOS/Darwin at least it only fails when run.

Reported upstream as #75617
