There is hardly anything as this setting was mostly superseded by the
use of libigloo. Which happened since the last beta (while super
stable, it's still a beta after all for exactly this type of reasons
:).

Adding the "linux" profile as you did should do the trick just fine for
the version you are running.

Also this is not really TLS related. This is for everything that needs
random numbers that is not TLS. (And therefore also applies to non-TLS
builds).


With best regards,
