-- luac is broken in some distributions, and cannot take more than one
-- argument without crashing on a double free or similar. this
-- completely breaks the cortav build process, so we supply our own
-- ultra-simplistic and painfully primitive luac replacement.
-- this does not generate very good object code.
-- pass luac-broken=1 when building to use
