Embedding within other programs is pretty much Lua's main selling point.
You don't use lua.c at all, just the functions present in lua.h (and
whatever other .h files needed for the particular application)

Not sure it'd be a good idea to combine lua and luac together either, as
luac needs the main Lua lib statically linked, where lua needs it in a
separate so/DLL file for external libs to link against.
