A few months back there was a big community fuss regarding direct-use

of the intel RDRAND instruction.  Consensus was RDRAND should probably
only be used as an additional source of entropy in a mixer.

Guess which library bends over backwards to provide easy access to
RDRAND?  Yep.  Guess which applications are using this support?  Not
even one... but still, this is being placed as a trap for someone.

Send this support straight to the abyss.
