This seems like an odd result considering the BeagleBone Black
processor is closer to a NEON. This particular BBB is running a Debian
8.2 based image.
I also believe CFLAGS should include hard-floats (i.e.,
-mfloat-abi=hard). Without it, entropy estimates for some of the RAND_
functions could produce incorrect results.
