[stunnel-users] Stunnel 4.56 and FIPS

Many thanks Mehmet. Compiling openssl with the "shared" option helped. That
resulted in the stunnel build process generating an stunnel executable that
dynamically linked to libcrypto.so. With this configuration, the FIPS
fingerprint is embedded in the shared library itself and the FIPS
self-verification step succeeds.
Without the "shared" option, stunnel was linking in libcrypto.a statically.
With this configuration, fipsld is needed to embed the FIPS fingerprint
into the stunnel executable at compile time. However, this does not appear
to be currently supported by the stunnel build process.
The reason openssl (application) worked in my examples below is that the
openssl build process does support FIPS in both configurations: as-is when
dynamically linked, and with fipsld when statically linked.
