FC_CHECK_READLINE_RUNTIME() does AC_RUN_IFELSE() to determine if readline is usable at runtime.
Maybe we should have a cache variable defined for this (as part of general idea that *all* AC_RUN_IFELSE() uses should have one), though not a high priority for the following reasons:
- The default (current value *always* used when cross-compiling) seems to be that readline is assumed to work. So this is *not* currently disabling readline support.
- There's --without-readline configure option to disable readline. That can be used when it's known not to work
