[Samba] Samba not seeing any interfaces

I've built samba for an embedded mips platform. Since this is an
embedded platform, it's possible that some critical file that samba
needs is missing but stracing the daemons doesn't reveal anything strange.
It's running 2.4.34 kernel.
Samba is failing to find any interfaces.

I added some debug lines to the interface.c routines.

It turns out that get_interfaces returns -1 - eventhough there is an
interfaces = line in smb.conf. From looking at the code, this is not
handled at all in interface.c.

Any idea why the kernel wouldn't return any interfaces?
