No, this did not solved the problem; build still fails.  The problem is
that, in lib/nlattr.c, we have:

#ifdef CONFIG_NET
...
EXPORT_SYMBOL(nla_put);
...
#endif

So, I still have an undefined reference to nla_put.

BTW, I'm not talking about the -next tree, so this problem may or may not
be the same one reported by Stephen.
