make linux-readline

["John Gabriele" <jgabriele@...>]

Hi,

I see that Lua 5.4 has a new platform target: linux-readline.

When building versions of Lua prior to v5.4 for linux, did the build pull in
readline if I had libreadline-dev installed on my system?

When I build 5.3, I see in the make output:

    gcc -std=gnu99 -o lua   lua.o liblua.a -lm -Wl,-E -ldl -lreadline

and running the repl I see that I get the usual expected support for
what I understand to be readline support (up and down arrows work,
^r works to search back, etc.).

What's the difference between 5.4's linux and linux-readline?
