Fix auto4/auto3 (lua51/lua50) support, this removes the --with-* flags in favor

of LUA_(C|LD)FLAGS and LUA50_(C|LD)FLAGS, also add the LUA LDFLAGS to LIBS like
perl in order to have it bring in the symbols properly, this is a temp measure
until we have modules.

Originally committed to SVN as r2082.
