Error compiling misc-progs in ARM aarch64.

[oliver-almaraz]

I tried running these examples in two different ARM aarch64 kernels, but I got the same error after running the main Makefile. I built only the misc-modules dir with the Makefile in it and it worked. Apparently, the problem lies inside misc-progs.
First kernel I tried with (Raspberri Pi 4B):

5.4.83-1-MANJARO-ARM #1 SMP PREEMPT Mon Dec 14 08:37:33 CST 2020 aarch64 GNU/Linux

Second one (Jetson Nano):

4.9.201-tegra #1 SMP PREEMPT Fri Jan 15 14:41:02 PST 2021 aarch64 GNU/Linux

After cloning and running the main Makefile I got:

[oliver@ManjaroARM ldd3]$ make

I know aarch64 is not a "standard" kernel, but I would be great to run all the examples in a cheap computer.
Thank you.

May this patch help you?

Probably relates to #66. I suspect there's work to do here to get everything running on aarch64. Pull requests welcome.
