Add -Bdynamic to your command line, e.g.
 mingw32-g++.exe -o result.exe main.o -s -lssh2 ... -Wl,-Bdynamic
but this should not be necessary. If libssl.a and libssl.dll.a exist then -lssl selects
libssl.dll.a by default.

You could also link to the DLL directly , e.g.:
mingw32-g++.exe -o result.exe main.o -s -lssh2 /path/to/ssl2.dll ...

Why do you think that you are not linking to dynamic  libraries now? If you run
$ objdump -p | grep "DLL Name:"
what do you see?
