I'd just use SYSCFLAGS and SYSCFLAGS. And you need to use LUA_USE_LINUX
if you want dynamic libraries and LUA_USE_READLINE if you want readline
support:

freebsd:
	$(MAKE) $(ALL) SYSCFLAGS="-DLUA_USE_LINUX -I/usr/local/include" SYSLIBS="-L/usr/local/lib -Wl,-E -lreadline" CC=cc

The question remains whether you need to add "-ldl" to SYSLIBS. The bsd
target does not include "-ldl" and so I guess the same applies to freebsd.

Note that LUA_USE_LINUX only does this in luaconf.h:

#if defined(LUA_USE_LINUX)
#define LUA_USE_POSIX
#define LUA_USE_DLOPEN          /* needs an extra library: -ldl */
#define LUA_USE_READLINE        /* needs some extra libraries */
#endif

There is nothing really specific about Linux here.
