Link fail

[dominions]

sgxsdk verison:2.12
sgxssl verion: 1.1.1i

I use EVP_* (such as EVP_CIPHER_CTX_new ) functions inside the enclave. Something wrong during the enclave's link phase.

GEN => App/Enclave_u.c
CC <= App/Enclave_u.c
CXX <= App/App.cpp
LINK => app
GEN => Enclave/Enclave_t.c
CC <= Enclave/Enclave_t.c
CXX <= Enclave/Enclave.cpp

I have fixed this issue by linking the library libsgx_pthread.
The issue occurs after I update the Intel sgxsdk and sgxssl. It seems that the old version doesn't need to link this library.

Same issue with Linux 2.13 SGX SDK OpenSSL 1.1.1i, fixed by adding -lsgx_pthread, thanks for your solution.
