This is valid only for the stripped down buildin readline of gnuplot.
'readline.c' compiles to nothing if you request for GNU readline.  See

Have you ever done 'configure --help' ?
Then you see (only relevant parts)

--enable and --with options recognized:
  --with-readline         use the included minimal readline function (default)
  --without-readline      do not use the included readline function
  --with-gnu-readline     use the GNU readline library
  --with-gnu-readline=PATH        Specify the location of GNU readline
  --with-plot             use the Unix plot library
  --with-plot=PATH                Specify the location of GNU libplot

And this qay you can switch on the use of libreadline and libhistory
from for example GNU readline-4.0.

And this is the common way to define additional libraries.
