Yes, if you want it to inherit from the optimisation flags used by the rest of Nmap i.e.:

CFLAGS="-O2 -march=pentium -mtune=pentium" \
./configure

Or else you have to edit liblua's Makefile each time to do that. Autoconf defaults to "-O2 -g" which isn't very different from the "-O2 -Wall" which is what liblua uses for optimisation flags without my patch. Liblua's specific CFLAGS are handled by LUAFLAGS. A better solution would be to define global optimisation flags probably, but that would require more "surgery" ;)
