  There are the environment variables LUA_PATH and LUA_CPATH that can be
used to modify the search paths.

It seems to me that this kind of thing is exactly the kind of thing that luaconf.h is there for; don't be afraid to hack it. It was never meant to be the canonical source of Universal Truth across all Lua builds everywhere. You want to build a custom configuration, so you have to customize the configuration.
