Many thanks for the patch!

I had no problem compiling it on ARM, and I ran it with no problem on an
example job file:

[random-writers]
ioengine=libaio
iodepth=4
rw=randwrite
bs=32k
direct=0
size=64m
numjobs=4

Now, you may modify the README file to mention that the ARM platform is
supported too.

Thanks again,

Cheers,

Michael.
