One thing I've not tested, is isolation from system SSL libraries
that don't employ symbol versions. Debian has been doing symbol
versions for a long time, so I never needed to worry about that.
And OpenSSL 1.1.0 has symbol versions on most platforms.
I would assume that Solaris also has symbol versions for OpenSSL
1.0.x, but if it does not and that's the system's SSL library, then
the variant build might not happily coexist with indirect dependencies
in other shared libraries, haven't tried that. Regardless, you're
no worse off than with the default SONAME and symbol versions.
