patch file

I found an issue with SCTP support in OpenJDK8 for FreeBSD. In my example 

https://github.com/msvoelker/java-sctp/

it happened that OpenJDK8 calls sendmsg with an buffer address != NULL and a
buffer length of 0, which is an invalid argument for FreeBSD. I found the code
lines in the function Java_sun_nio_ch_sctp_SctpChannelImpl_send0 of

jdk/src/solaris/native/sun/nio/ch/sctp/SctpChannelImpl.c

Besides that, I changed two ifdef statements for FreeBSD (see attached patch
file). If I copy this patch file to the files directory of the OpenJDK8 port,
I'm able to install OpenJDK and to run the example application.

sudo cp patch-jdk-src-solaris-native-sun-nio-ch-sctp-SctpChannelImpl.c
/usr/ports/java/openjdk8/files
cd /usr/ports/java/openjdk8
sudo make install

I just saw that hwh found this issue already for OpenJDK7.
