Better would be

LUA_VERSION = $(shell $(LUA) -E -e "print (_VERSION:match '^Lua (.*)')")

or maybe (because 5.1 doesn't have -E)

LUA_VERSION = $(shell $(LUA) -e
"io.stdout:write(string.match(_VERSION,'^Lua (.*)'),'\n')")


LUA_INIT (if defined and not disabled by -E) runs first and can
add/remove/replace a lot of things.  Don't depend on print producing
"dumb" output if there's LUA_INIT.  (The Lua REPL uses whatever _G.print
is to output results, so my 'print' colors values by types, adds
metatable info etc. etc. - resulting in some really funky directory
names if used like that!)
