a similar build bug happens with latest -git as well, with SCTP:

 net/built-in.o: In function `rxrpc_destroy_s':
 ar-key.c:(.text+0xc5a2b): undefined reference to `crypto_free_tfm'
 net/built-in.o: In function `rxrpc_instantiate_s':
 ar-key.c:(.text+0xc5ed9): undefined reference to `crypto_alloc_base'
 net/built-in.o: In function `sctp_endpoint_put':
 : undefined reference to `crypto_free_tfm'
 net/built-in.o: In function `sctp_inet_listen':
 : undefined reference to `crypto_free_tfm'
 net/built-in.o: In function `sctp_auth_destroy_hmacs':
 : undefined reference to `crypto_free_tfm'
 net/built-in.o: In function `sctp_auth_init_hmacs':
 : undefined reference to `crypto_alloc_base'

this is a build regression over v2.6.23. config attached.
