My suggestion is this:

Build with lauxlib and also build the standard libraries
Create a new sysctl kern.lua.stdlib, set to one by default
If a new state is created in lua(4), run lua_openlib(...) on that state
if kern.lua.stdlib is set to a vaue != 0

So by default a kernel Lua state would then have the stdlibs available,
much you have them available when running lua(1).
