It was more of a "there doesn't seem much overhead to supporting both,
since the API is the same".  I think the Makefile should take an
approach more like this though:

	ifdef NO_LUA
	else if defined(USE_LUAJIT)
		# LuaJIT code goes here
		# Lua code goes here

Basically, use vanilla Lua by default by provide an easy way for users
to switch to LuaJIT if they want.
