libcrypto/openssl : Which to use

[Aditya Kousik]

It's a weird scenario that I had the exact same epiphany, at about the same
time. I found that all cryptopp/* files have such #defs. Primarily done in
cryptopp/config.h, there's a #if defined(__unix__) then #define
OS_RNG_AVAILABLE, and so on.

So, you may need to contact GCC and ask them to add __genode__ for the
defined preprocessor. But, with your help, I've discovered a way to
proceed. Thank you very much, I'll keep you updated.

Cheers,
Aditya
