Ok, I read a bit more. I think we need it.

But the documentation should be amended (this is an OpenSSL feature).
This also goes for --random-file which is only used in src/openssl.c.

GnuTLS is configured to read from (egd/prngd) files at compilation time from 
what I read so far. Or does someone know a way to set a random data file 
explicitely for GnuTLS ? If yes, we should use it if the user requests it.
