It might make sense to define its meaning clearly one way or another,
though, no? Otherwise, even if LuaRocks does not use it internally,
there is a risk of different rocks making different assumptions, some
assuming LUA to contain a full path while others assuming its just the
name and thus prepending $LUA_BINDIR to get the full path. It would
then become necessary to change the config file between installing
different rocks, which sounds undesirable.
