It looks like a recent commit to update the version of SeaBIOS used
broke the build as the qemu mirror hasn't been updated yet. You can work
around it for now by patching .gitmodules:

commit 7149af13dd5600b27dac90235e60ff91d0468636
Author: Alex Bennée <alex@bennee.com>
Date:   Tue Oct 1 16:51:38 2013 +0100

    .gitmodules: use upstream SeaBIOS repo to fix submodule init
    
    Currently master is broken as the wanted commit doesn't exist in
    qemu's mirror of SeaBIOS.
