In recent years AMD CPUs have had various problems with RDRAND
giving either non-random data or no result at all, which is
problematic if either build or target machine has a CPU with
this problem.
The fallback is /dev/urandom, and I'd trust the kernel here.
--enable-rdrand was added in an upgrade to a new upstream
version without mentioning any reason.
