Try linking Lua without readline and possibly static.

This line:
 time for in in `seq 1 1000`; do lua -e return; done

takes
 2.0s standard linux build (dynamic, with readline)
 1.4s dynamic without readline
 0.9s static without readline

on an old 3GHz-P4.  0.02s (20s for 1000) looks like a really slow
machine or something strange's going on.
