The shipped defconfig also does not work for me. I don't think, that 
this is a .config problem.
At least, when I reverse commit 
983c6a606bc839248ea0c69090e60c095a655bc6, I can compile it.

"Use OpenSSL HMAC_* functions to implement HMAC-MD5 instead of depending
on the src/crypto/md5.c implementation."

Due hmac_md5 and hmac_md5_vector definied both in crypto_openssl.c and 
md5.c that happens.
So, why is it during compiling including both?
