Flex: the fast lexical analyser

Flex is a dependency for Wide-DHCPv6.

Download flex and cross compile for ARM assuming your ARM cross compiler is located at /opt/arm-2011.09/

http://downloads.sourceforge.net/project/flex/flex-2.5.37.tar.bz2
tar -xjf flex-2.5.37.tar.bz2
cd flex-2.5.37/
./configure --host=arm-none-linux-gnueabi --prefix=/opt/arm-2011.09/arm-none-linux-gnueabi
make
make install

Cross Compiling Wide DHCPv6 for ARM

Wide-DHCPv6 has not been updated for some time and uses structures no longer avaliable in glibc without the use of the #define _GNU_SOURCE

Instead, we patch it with a patch developed by Jeremie Corbier
