Build fail on aarch64

Additional context

@ggardet I don't officially support ARM, unfortunately, and heim, the library that is failing to build, also doesn't officially support it as far as I'm aware. I just realized my README might have been a bit misleading, I've corrected it - I only support x86 and x86-64 since that's what the libraries I use support.

That being said, I could potentially look into seeing if there's a way to get it to build on ARM... if it's just heim that's having issues, I could see if it's potentially possible to replace heim's usage and just not use the library on ARM compilations... guess I'll bust out the Pi and have a crack at it after I fix some of my current issues.

I get the exact same error.

@ggardet @Titaniumtown could you try cloning the master branch and see if you can get it to build? I've gotten it to build now on a Raspberry Pi 4 and an Opensuse Tumbleweed Aarch64 VM.

Note it's not perfect yet (for example, disk read/s and write/s doesn't work yet, I have to implement that myself), but it should at least compile and mostly work from testing it a bit.

[ggardet]

It complains about anyhow missing:

 error: no matching package named `anyhow` found

Is it a new dependency?

[ClementTsang]

@ggardet I'm using it for error handling, yes.

@ggardet I'm using it for error handling, yes.

I am not good enough in rust packaging to add it to the vendor archive to build it in Open Build Service.
But if you have it built on openSUSE Tumbleweed aarch64, that's fine then.

Going to close this for now, since while I'm still not officially supporting ARM builds yet, it should build correctly now, and I run Travis checks to ensure it will. Feel free to re-open or create a new issue if it fails again, or doesn't properly work, or if you have any other questions that aren't about the build failing.
