OpenSSL dlopen abort error

Disclaimer: I already read the issue here with an similar name, but the solution there (adding the no-engine and no-dso parameters) did not work for me.

My plan was to have a ssl connection running on top of a emscripten websocket bridge so i can do end to end encryption like i did in my native project. I have a simple openssl server running (port 7777) and also the websocket_to_posix_proxy (port 8088).

I successfuly compiled openssl with emscripten using the following script:

```
#!/bin/sh

OPENSSL="openssl-1.1.1d"

if [ -d ${OPENSSL} ]; then
rm -rf ${OPENSSL}
fi

if [ ! -f ${OPENSSL}.tar.gz ]; then
curl -O https://www.openssl.org/source/${OPENSSL}.tar.gz
fi

tar xf ${OPENSSL}.tar.gz
cd ${OPENSSL} || exit 1

emconfigure ./Configure \
linux-generic64 \
no-asm \
no-engine \
no-hw \
no-weak-ssl-ciphers \
no-dtls \
no-shared \
no-dso \
--prefix=$EMSCRIPTEN/system

sed -i 's|^CROSS_COMPILE.*$|CROSS_COMPILE=|g' Makefile
sed -i '/^CFLAGS/ s/$/ -D__STDC_NO_ATOMICS__=1/' Makefile
sed -i '/^CXXFLAGS/ s/$/ -D__STDC_NO_ATOMICS__=1/' Makefile

emmake make -j 1 build_generated libssl.a libcrypto.a

cd ..
```

Then i tried linking it statically so i can use the openssl api on top of posix socket.

```
em++ -std=c++17 \
-s ALLOW_MEMORY_GROWTH=1 \
main.cpp \
lib/libssl.a \
lib/libcrypto.a \
-I E:\DATA\Libs\openssl-1.1.1d\include \
-o test.html
--shell-file html_template/shell_minimal.html \
-s EXPORTED_FUNCTIONS="['_main']" \
-s ASSERTIONS=1 \
-lwebsocket.js \
-s PROXY_POSIX_SOCKETS=1 \
-s USE_PTHREADS=1 \
-s PROXY_TO_PTHREAD=1 \
-static
```

My c++ code is just like in the sample "tests/websocket/tcp_echo_client.cpp".
But instead of sending data i try to open an tls connection:

```
#ifdef __EMSCRIPTEN__
bridgeSocket = emscripten_init_websocket_to_posix_socket_bridge("ws://localhost:8088");
// Synchronously wait until connection has been established.
uint16_t readyState = 0;
do {
emscripten_websocket_get_ready_state(bridgeSocket, &readyState);
emscripten_thread_sleep(100);
} while (readyState == 0);
#endif

//lookup_host("google.com");

// Create socket
int sock = socket(AF_INET, SOCK_STREAM, 0);
if (sock == -1)
{
printf("Could not create socket");
exit(1);
}
printf("Socket created: %d\n", sock);

struct sockaddr_in server;
server.sin_addr.s_addr = inet_addr("127.0.0.1");
server.sin_family = AF_INET;
server.sin_port = htons(7777);

if (connect(sock, (struct sockaddr*)&server, sizeof(server)) < 0)
{
perror("connect failed. Error");
return 1;
}

SSL_CTX* ctx = InitSSL_CTX();
SSL* ssl = SSL_new(ctx);
if (ssl == nullptr)
{
fprintf(stderr, "SSL_new() failed\n");
exit(EXIT_FAILURE);
}

SSL_set_fd(ssl, sock);

const int status = SSL_connect(ssl);
if (status != 1)
{
SSL_get_error(ssl, status);
ERR_print_errors_fp(stderr); //High probability this doesn't do anything
fprintf(stderr, "SSL_connect failed with SSL_get_error code %d\n", status);
exit(EXIT_FAILURE);
}
```

I think the error im getting occurs at the `SSL_CTX* ctx = InitSSL_CTX();`.
The error is:
```
Pthread aborting at Error
at abort (http://localhost/test/test.js:1:24436)
at _dlopen (http://localhost/test/test.js:1:103187)
at http://localhost/test/test.wasm:wasm-function[1046]:0x55753
...
```

and also:
```
Uncaught RuntimeError: abort(To use dlopen, you need to use Emscripten's linking support, see https://github.com/emscripten-core/emscripten/wiki/Linking) at Error
at jsStackTrace (test.js:1)
at stackTrace (test.js:1)
at abort (test.js:1)
at _dlopen (test.js:1)
...
```

Also, i removed the -no-threads option from the openssl build script because i got a thread error. I dont know if that was the right way to do it and maybe this also has something to do with the problem im facing right now.
