maybe a little "configure" (shell) script (not autotools generated)
would help with build configuration (save its results in "config.h" and
make related flags in "conf.mk" (later sourced from the main makefile)).
default values could be provided in - say - "defconfig.h" and
"defconf.mk" then.

although i would not use readline at all to be honest.
this eases building. similar functionality is also provided by
external utilities like "rlwrap" and libtecla's "enhance".
those could be used for line editing instead. this has the advantage
that users can use the line editing library of their choice
(eg readline, editline, tecla, linenoise).
