something is wrong. for whatever reason there was a -DNO_SECURITY

that was always enabled, whether security was enabled or not. this caused
a confusion on the compile line, there -DMOZ_SECURITY and -DNO_SECURITY would
be simultaneously defined.
as a temporary hack, duplicate the logic on mozilla/config/config.mk
so that ifdef NO_SECURITY -DNO_SECURITY, else -DMOZ_SECURITY.

what a mess. this needs to be fixed right.
