  Starting with kernel v3.2.39, a Debian specific patch defines
eth_hw_addr_random() in include/linux/etherdevice.h, causing the build of
batman-adv to fail.

This patch fixes the build on these kernels while keeping compatiblity with
unpatched kernels by replacing batman-adv's compat definition of the
eth_hw_addr_random() function with a #define macro.

How about re-defining the function name and keep the static inline ? There are 
numerous examples of this in the compat.h file, for instance 
batadv_this_cpu_add().

We also might want a comment there that we do this for Debian compat. 

Cheers,
Marek
