Not our problem, I think.  The OS vendor would have to have fallen
down on the job quite badly to offer an OS-level "FIPS mode" while
shipping an OpenSSL that doesn't honor that.  It would not be optional
for OpenSSL to be in that mode if the OS is.

(If we end up inventing a FIPS-mode flag, I would fully expect
interested vendors to patch our code to force it on when the
OS-level flag is set, which is exactly what they will have done
to OpenSSL.  We should design our behavior with that in mind.)
