makefile: auto-detect presence of various Lua, bsd
We favor LuaJIT over Lua. We disable Lua if neither can be found. We error out if a particular Lua is specified via LUA_IMPLEMENTATION=JIT or LUA_IMPLEMENTATION=VANILLA, but cannot be found. We print a status message depending on what happens. Also, we do not link against libdl on the BSDs, since they include it as part of libc. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
