Fix linking order for OpenSSL libraries

As libssl depends on libcrypto, -lssl needs to precede -lcrypto in
linker invocations or else the build will fail with static OpenSSL
libraries.  Adjust m4/ax_check_openssl.m4 to prevent this issue from
getting triggered when pkg-config files for OpenSSL are not available.
