Neither approach is right.  The right approach is dynamic linking
against a version of OpenSSL that has symbol versions that avoid
conflict with other versions of OpenSSL, and perhaps use $ORIGIN
in the runpath to deliver the executable and library at related,
but relocatable paths.

With static linking (of just OpenSSL), you get potential ABI issues
with loadable modules (e.g. nss modules, or others), if the loadable
module uses and expects the system version of OpenSSL.
