OpenSSL libssl.so error undefined reference to 'ssl3_cbc_remove_padding'

I am currently patching a older version of OpenSSL to the latest stable 1.0.0o build (via import_openssl.sh)for use with a Android application via the NDK r10c.

While building the libssl.so sharedlibrary i am presented with the following errors.

[armeabi] SharedLibrary  : libssl.so
jni/openssl/ssl/s3_enc.c:542: error: undefined reference to 'ssl3_cbc_remove_padding'
jni/openssl/ssl/s3_enc.c:739: error: undefined reference to 'ssl3_cbc_record_digest_supported'
jni/openssl/ssl/s3_enc.c:764: error: undefined reference to 'ssl3_cbc_digest_record'
jni/openssl/ssl/s3_pkt.c:464: error: undefined reference to 'ssl3_cbc_copy_mac'
jni/openssl/ssl/t1_enc.c:763: error: undefined reference to 'tls1_cbc_remove_padding'
jni/openssl/ssl/t1_enc.c:919: error: undefined reference to 'ssl3_cbc_record_digest_supported'
jni/openssl/ssl/t1_enc.c:925: error: undefined reference to 'ssl3_cbc_digest_record'
jni/openssl/ssl/ssl_lib.c:1058: error: undefined reference to 'dtls1_min_mtu'

Taking the first error for example, i can see a reference in the file s3_enc.c (https://github.com/openssl/openssl/blob/OpenSSL_1_0_0-stable/ssl/s3_enc.c) to a function 'ssl3_cbc_remove_padding' but the actual function is nowhere to be seen, only a prototype in ssl_locl.h (https://github.com/openssl/openssl/blob/OpenSSL_1_0_0-stable/ssl/ssl_lib.c) so i am a little confused.

Any help or previous experience would be greatly appreciated in order to get these errors cleared. if you need me to elaborate further, please ask.

Check the files (s3_enc.c, t1_enc.c, ssl_lib.c), included in their respective .mk files or not. In my case it was not included so I just add these source files in ssl/Android.mk under LOCAL_SRC_FILES section.
