i think you misunderstood my report. This is about latest upstream -git 
being broken:

ERROR: "ebt_register_table" [net/bridge/netfilter/ebtable_filter.ko] undefined!
ERROR: "ebt_do_table" [net/bridge/netfilter/ebtable_filter.ko] undefined!
ERROR: "ebt_unregister_table" [net/bridge/netfilter/ebtable_filter.ko] undefined!
ERROR: "ebt_register_table" [net/bridge/netfilter/ebtable_broute.ko] undefined!
ERROR: "ebt_do_table" [net/bridge/netfilter/ebtable_broute.ko] undefined!
ERROR: "ebt_unregister_table" [net/bridge/netfilter/ebtable_broute.ko] undefined!
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2

i posted to this thread because i wanted to find a relevant context. 
(but probably is not)

Anyway, i started a new thread for this.

the dependencies there look pretty complex so i did not find a quick fix 
- but i can test patches.

config attached.
