++This script will convert all _init() functions on iptables extension sources in order
++to compile then on Android.
++This will for example, convert "void _init(void)" on libipt_LOG.c to "void libipt_LOG_init(void)".
++This is necessary because we cannot use the "-D_INIT=$*_init" on LOCAL_CFLAGS due to the way NDK works.
